lipsinc problems not restricted to Pinnacle
I have found that any analogue input via non proprietry hardware can give problems as there are usually 2 inputs.
1) vidoe via Video/ TV card
2) sound via sound card.
Try importing shorter sections of video and splice them during render as the lipsinc generally moves out further as the capture progresses
You can readjust the sinc by cutting and pasting the sound track (this can get messy
