5 out of 5 eggsGood product

Pros: Use this to watch television on your computer, tablet, or other device. It has 2 tuners, which means you can watch separate channels simultaneously with 2 different devices.

Cons: Signal is compressed, meaning there will be some pixelation. It's not too bad, but programs watched on a tv directly connected to an antenna will be uncompressed, and hence, will provide superior picture quality to this.

Some of your devices might not be able to find and use the device.

Other Thoughts: This device can be useful in a number of situations. For example, you could attach antenna #2 to this and watch tv on it when antenna #1 (connected to the tv) can't pick up your desired station. Or if you have cable connected to the tv you can connect an antenna to this for your over the air stations. Another use could be where there is a long cable run from the antenna to the tv, resulting in substantial signal loss over the length of the cable. You can connect this device close to the antenna and run a long network cable to it.

If your tv supports DLNA or UPnP it might be able to find and use this device. My LG DLNA tv can't find it, but my Sony Blu Ray player can. I got it to work on my android tablet with free apps, but haven't been able to find a free app to make it work on my iPad Mini. Haven't been able to get it to work on my Windows XP computer, but works fine on all three Windows 7 computers.

After a channel scan I always have to go in and manually rename a couple of the x.2 virtual tv channels in order to workaround a naming conflict. For example, both 15.1 and 15.2 come up as KADNTV and both can't be enabled at the same time until I rename the 2nd one to KADNTV2. Not a biggie, but I just wanted to include this workaround for those experiencing the same issue.

5 out of 5 eggsPicture is better than cable

Pros: I keep this device in the office where I have placed my antenna. I found a fractal antenna works best in my area. I'm about 30 to 40 miles away from the major networks broadcast, through tree and a fare size city (Charlotte). The picture is great better than cable. I use this device in conjunction with xbmc and nextpvr. Nextpvr works very good in recording our tv shows during the week. However I haven't found a good way to move the antenna automatically.

Cons: I find that weather can affect picture quality as well different seasons of the year. This device is slow changing channels. I find your better to stop the channel your watching then click on a different one.

Other Thoughts: HDhomerun config works great when adjusting antenna before shows start.

5 out of 5 eggsMuch improved reception

Pros: Small, Great signal detection. Good speed in changing channels. Dual tuners almost a must.

Cons: Like the original version this seems to go goofy once in a while. Unplug and it corrects. Maybe 6 months or longer so it isn't terrible.

Other Thoughts: I complained about the original's lack of signal detection ability and they fixed it here. I'm waiting on a version that goes outside and connects to an antenna next.

5 out of 5 eggsworks like advertised

Pros: Works very well. Crystal clear picture when signal is strong enough.

Cons: Some other reviewers have claimed that the tuner sensitivity is better than previous generation. I strongly disagree. I get the same signal levels on both generations when hooked to same antenna. Unfortunately, that was the whole reason why I upgraded. Don't believe the hype. No point in upgrading.

Other Thoughts: DLNA is nice but I have yet to find a use for it.

4 out of 5 eggsCrystal Clear

Pros: Easy setup, good reception, low power consumption

Cons: The Android app is appalling (not to mention not included).

Other Thoughts: I have this in my attic where the temperatures easily get over 35 (in the American West), still going strong. The device uses the MPEG2 codec so if you're like me and using a Raspberry Pi as an XBMC host, you'll need to purchase the appropriate license from them.

5 out of 5 eggsLove this gadget!

Pros: Works great. I hooked up my antenna cable and plugged the ethernet cable into HDHomeRun and my switch. Assigned a static ip address to the HDHomeRun and home PC, windows media center saw it right away and within minutes i was watching tv on home pc.

Cons: none

Other Thoughts: windows media center records tv with a .wtv file extension. i have found that, in my case, our PS3 will not play this type of file. Uggg... just when i start to like microsoft another brick get thrown my way. So, there are many avenues you can use to decode/transcode this type of nasty file (.wtv). ffmpeg - you can read about, or google, plex media server will transcode the file, although put those nasty .wtv files in a movie folder ** not a tv folder **, otherwise plex will not trascode them - i do not know why.. hope this helps some people out there... enjoy....

5 out of 5 eggsCompletely Cool

Pros: Such a great solution to watch or record digital TV (2 channels at a time) bypassing all the internet hassles by capturing the broadcast directly from the broadcaster. Hooked it up to my old TV antenna, and plugged into a network cable in ... ran the setup to scan all the available stations ... ran the Window Media Center setup. So cool. It just works.

Cons: none for me

Other Thoughts: Tried some of the alternatives to Window Media Center which ended up being kind of complicated. Just needed more time to thoroughly understand the other setups. Window Media Center works great.

5 out of 5 eggsJust what I needed for MythTV

Pros: Works perfectly with MythTV 0.27; tunes basically any channel, any time as long as you set the tuning delay to 5000ms. Good tuner sensitivity. Handy built-in splitter means two tuners with only one cable connection. Signal strength meter actually works!

Cons: Incredibly small and light, with no wall mounting keyholes. Double-shielded coaxial cable lifts the thing up!

Other Thoughts: Only tried it with MythTV, so I can't comment on how it works with eyeTV or WMC. Uses about 50mbs when recording two high-def shows, so plan your network accordingly.

5 out of 5 eggsWorks so far...

Pros: * Strong signal strength
* Works well with Windows Media Center

Cons: * WMC & HDHomeRun QuickTV' don't use DLNA

Other Thoughts: I use this device on a wired desktop PC & a laptop that's connected via wifi.

The desktop PC doesn't have any issues at all & works very well with every media player application that I tested.

The laptop was a different story (at first). The laptop's wifi connection is strong (connected @ 180mbit) & usually achieves a real-world throughput of ~70mbits, but WMC & 'HDHomeRun QuickTV' were stuttering frequently on HD video feeds. The bandwidth that this device requires to stream a 1080i video feed is 12mits to 20mbits, so I was initially confused at why the video was so stutter & artifact prone since my wifi is capable of meeting the bandwidth requirements. As I looked into it, I noticed that WMC & 'QuickTV' both use a UDP based protocol to get the video feed. 'High bandwidth usage on wifi' + 'UDP' = 'error prone video'.

Luckily, this device supports DLNA (which is TCP based). Windows Media Player supports DLNA natively, but WMP wanted to spend a lot of time buffering before playing the video feed (though after it buffered, it played smoothly). The answer to my problems was VLC. In VLC, access the DLNA feeds from Playlist -> Local Network -> UPnP. Using VLC, 1080i video feeds play completely stutter & artifact free on my laptop. At the time of this writing, all versions of VLC that are older than 2.0.8 have a bug in them that breaks UPnP, so I'm stuck on VLC 2.0.8 until this bug is fixed. However, VLC 2.0.8 works perfectly fine for me, so I'm a happy customer at the moment.
