I will check about the same points in the recording. For now, all I know is that I captured a 47 min. concert video and one of the places it dropped frames was in a fast camera sequence from the guitar player to the group, but the other placed was in a slower area with fades and pans. I had to trash the entire capture due to it being not fit to put on a DVD. I ended up capturing with Elgato Video Capture and using iDVD to author the DVD.
It would be beneficial to use the Roxio product if it worked without dropped frames if you were definitely going to DVD and nothing else. VHS resolution is roughly 320x480 pixels so both products can easily get a nice capture, but if going to DVD the Roxio device would be preferred since it captures in MPEG-2 if it can have the dropped frame issue resolved.
I will try and get a short sample of a new MPEG-2 encoding if you desire that.
