Vision Express TV Capture - Frame Loss



When capturing TV from an TV card with Nero Vision Express 2, it works fine for about 3 minutes, then massive frame loss starts (about 50% of the frames lost). Such video is unusable.

I have tested the same with Ulead VideoStudio 7: It worked fine for the 10 minutes test (UVS7 does not indicate captured/lost frame numbers as Vision Express 2 does, but the captured video looked totally OK).

Has anybody experience with TV capture with Vision Express 2? Are there specific settings I have to adapt?
