I'm using Power Director 7 to convert VHS tapes to MP4. The whole system worked like a charm yesterday but today when I press 'record' to capture the video it runs for 3 or 4 seconds and then the clip becomes jerky. If I turn off the PD 'record' the tape continues to play and its not jerky....but its also not recording. The clip that's saved in PD7 is jerky. I've cleared the cache, run a defrag. Any suggestions? Its so frustrating ..c::
