Lol another owner of a Pixelview BT878P+ from past 4 years. Yea its a crappy card from todays standard, the PVR software sucks, low resolution, not easily configurable if you are doing it fot the first time, But there is one thing for sure in that card and the pixelview playtv pro software. I currently have that card installed on my brother's PC and he keeps his system on for days at stretch and the app just never crashes, nothing of the sound lost but video going on or viceversa, or any other issues we normally face when we mess with these tvtuners switching the pvr softwares.
As for installation in Windows 9x and 2k/XP, its pretty much the same and works too.
