? ? ???Help! I just installed a win tv pvr usb2 into my system. it appears to work fine with win tv 2000, but as soon as i try to run it on Media Center, it #1) has no sound. #2) after a minute or so the picture locks and i get a completely distorted picture with a separate moving multi color band on the bottom of the picture. i installed it right, when i first start the media center i get a fine pic, but no sound... then if i change the channels after about a minute it goes totally whacked. what do i do? i like the tv tuner much better on the media center, but as it stands... i am stuck using the wintv 2000. i have reset the channels three times, i have changed the audio settings to every possible setting, and still nothing. if anyone out ther can help me along i would be very greatful. Thanks ahead of time,r ? ? ?
