Summary: We bought this in April, and it has stopped working completely (it's July). We had trouble with the various setup instructions to get everything just right so it actually worked with both OTA tv signals and the RCA ports in the front. Getting it to work with WMC took a lot of work. The biggest downside is that we quickly realized it would need to be unplugged and plugged back in (to reset) every time the computer was turned off or rebooted.
Summary: I enjoy the digital tuner so I can a view my favorite channels. I am not pleased with the WIN7 TV software, it has less flexibility compared to earlier version, I like to be able to record in Mpeg 1 format (VCD) to reduce storage space. The software do not allow changing encoding formats. The hardware does work well with windows 7 MCE.
Excerpt: Using with Win 7. Wanted to set it up as a head end for XBMC PVR. The Win TV software is a bit weird. I found that it will NOT co-exist with Skype if you have a video camera. I have to log off Skype if I want to record anything. Also, recordings are not very reliable unless you tune the channel manually. Hard to evaluate the hardware independant of the software. Hauppage is normally quality kit, and I see no reason to change that opinion.
Summary: I just got this in a few days ago so I am not making a full report. I'll have to remember to come back and update. It was easy to setup out of the box. I use Media Center so I did not istall the TV app, but I did downlaod and istall the latest drivers from the Hauppage site. I replaced a VisionTek TV Wonder 650 USB TV Tuner as it was causing issues with windows 7 and there are no win 7 drivers available for it. So far, so good.
