I imported my .m2v video file in Premiere, but as I started editing it, I noticed that it skipped (and repeated) a frame every now and then. I'm pretty sure that it's not the pre-vis window lagging: I see them when I go frame by frame. I guess it's also affecting the audio sync. Does anybody have any idea why it does that / how to fix it?!

Is it one dupe frame in every five? That's typical of bad IVTC - i.e. the stream is 29.97fps when it should be 23.976fps.

Ok, I imported the file in Premiere again and now, the movie is inexplicably sped up.... It's supposed to be 1:30 and it's now something like 50 min...It jumps and lags and I don't know what's going on.

I had a similar skipping and speed issue in Premiere; Premiere apparently doesn't read the ripped m2v file well regardless of whether you are using a 30i or 24p project.

Read through ADigitalMan's MPEG Editing Guide, and transcode your m2v file to an uncompressed AVI if you can spare the drive space.

This is how I'm editing my DVD rip in Premiere. Otherwise, you can edit the m2v directly in Womble MPEG Video Wizard after you error-correct the file.

In the guide, ADigitalMan says :

1) Export just the two shots you want to crossfade to an M2V file.
2) Load the clip into VirtualDubMod and save as an uncompressed AVI.

Problem is, Virtual Dub can't read M2v or MPG files, no? How can I import the m2v file and convert it to an uncompressed (loss less) avi for Premiere?

Well, ADM gives you the process to convert an M2V to an uncompressed AVI though the guide assumes you will be editing your final cut in Womble.

I decided to edit my entire movie in Premiere, so I used the process of creating the uncompressed AVI from the M2V as ADM explained it in "Step 3"; the only thing I didn't do as instructed when editing the AVS file was the cropping command since my source (the movie) was already in 16x9 aspect ratio. You still need to edit the LanczosResize line, though.

Read through the guide thoroughly with your thinking cap on, and hopefully you'll get though the process successfully and more quickly than I did when I impatiently ran through it. Hope this helps.

Correct, VirtualDub cannot read MPEG-2 files. However, as ADigitalMan says, VirtualDubMod can. You can also use VirtualDub-MPEG2 which is a bit more up-to-date than VDubMod.
