i have pinnacle pctv card on my system.it was working fine bt recently the software started hanging.i installed/uninstalled pctv vision/stereo many times bt when pctv assistant runs it shows device test failed.when i start pctv vision it shows that software has encountered a problem and need to close.i have even downloaded the recent version of pctvstereo from the net but that too didnt helped.ihave even downloaded seprately all the drivers required to run the application but it came to no use.
the device manager also shows an unknown device whose location is on "SAA7134 TV Card - Video Capture".the 'device instance id' is: STREAM\7134TVTUNER\5&11EC8734&0&0
