yeah I remember that too but the new nvidia drivers fixed that as far as i know I have no problems the original software that came with my hdtv wonder card "mmc". I also can get it to work in windows media center with kram drivers and I dont have a problem.
I dont get errors anymore instead when I go to record it just freezes media center. The only way to close the program is to press cntrl+alt+dlt. To make errors go away and my atuo search for dtv channels to work I did the following:
1. Installed newest ATI hdtv wonder drivers, rebooted.
2. Installed purchased version of nvidias PureVision decoder, rebooted.
3. Installed purchased JRiver Media Center 11.0.314, rebooted.
This seemed to get everything working except timeshifting and recording. when Time shifting is enabled I get an error saying "failed to load timeshifting files". And when I press record My program freezes or says unknown error. I cant figure out why I cant record HDTV. Please any suggestions?!
