Okay, so I followed the guide from mediaguru. I'm using MTR 2.6.6 and Toast 7 (no compression software because the file is only 262MB). I'm only trying to make a DVD copy of just 1 chapter. I've thoroughly read the MTR pdf manual for extracting individual chapters, but to no avail. When I play it with DVD player I get a system error: "could not detect a valid media file -70001." Tried several times. Also tried dragging the VIDEO_TS folder into Toast under the video>DVD video from VIDEO_TS and it says "this is not a valid VIDEO_TS folder, it cannot be selected." Tried multiple DVDs, and different extractors (OSeX, DVDBackup 1.3) for the heck of it. What am I doing wrong?!?!?
