I'm trying to get my HVR-1600 tuner working. I'm running Windows 7 Media Center 64-bit on a Dell Optiplex 960 with an Intel E8600 Core 2 Duo processor at 3.33 GHz, 4 GB RAM, 250GB hard drive, with a Dell/NVidia GeForce GT330. Drivers are up to date. The TV Tuner is a Hauppauge HVR-1600. This is running on a 100% clean install of Windows 7.
My issue is:
Certain HD ClearQAM channels do not work. Others work fine.
KWWL (114.1 1080i) and its subchannels (114.3 MeTV, 114.2 This, both 480i) work very well. No stuttering at all
KFXA (115.4 720p) has a ton of stuttering/pixelation
KGAN (114.6 720p) works well, as does subchannel 114.8 GetTV
KCRG (115.2 720p) does not work. KCRG 9.2 (115.6) and 9.3 (115.10) also are unwatchable due to stuttering/pixelation. 9.3 is especially bad.
What could be the issue here? It doesn't seem like its 720p vs 1080i, because some 720p channels work fine, others are unusable.
The stuttering shows up on recordings, just as it showed up live.
Any ideas?
