Sorry for the horribly newbish question, but I'm lost on this issue, and the guides I have read aren't clearing things up.

I am editing a movie. A short section (1 minute) of one of the vob files is unusable, but luckily I have a PAL version from which I can extract the segment I need. However, I need to make sure this won't cause problems in the finished DVD - i.e. I need the framerate for this mpeg to match.

I used Womble MPEG-VCR to extract the part of the vob I need at the PAL standard 25 FPS. So far, so good. MPEG-VCR also allows you to change the framerate on the video if you want, so I saved a second version at 29.97. It looks fine and the audio appears to be synced; basically I can't see or hear anything wrong with it. Considering the somewhat complicated guides for doing this sort of conversion, I'm not sure if I'm missing something minor that is wrong with the file. I'd like to know this before I use it in my final movie. Is the audio at a different pitch and I am just unable to detect it? I've got adjacent lines of dialogue in the clips - I figured the change would be audible, but it's not.

Also, one odd footnote: if I pull this mpeg into Womble MPEG Video Wizard (the editor I am using), it appears to have a different aspect ratio than my other files. Everything should be 1.85:1 but when viewed in their preview window, all my other files appear correct & letterboxed, while this one looks stretched out to fill a full screen. I couldn't figure out why, but when I made a test mpeg of the whole movie, this section blended right into the rest at the same aspect ratio. I don't get that part, but if it works, it works (I guess).
