The peak file hung up when using captured files from Roxy or Movie Maker-- apparently due to the fact that the video tape ended before the actual tape end -- The capture software apparently does not stop when the video ends but keeps going until the end of the tape even though the time code is 0.
To correct this, I found that saving it in movie maker to a new file worked as it cut out timecode 0 portion.
I also have a problem with capturing in Premiere (which is why I'm using this other capture software). -- see other topic -- I need help on this!!!
