vegas imports dvd with ac3 inside mpg

[codemaster]

I use a Canon camcorder that encodes the captured footage to mpeg2 and ac3 directly, in real time, and writes it to a mini dvd optical disc. After I finalize the mini dvd disc, and insert it into a dvd-rom on a PC, I can see that there is a VIDEO_TS folder, and inside it, there are .VOB, .TS and .BUP files.

The camcorder creates a dvd menu with a button for each individual clip, but all individual clips are stored in one continuous .VOB file, in one VTS, and Sony Vegas is able to import each individual clip into separate .mpg files.

However, it seems strange to me that Vegas is using the .mpg container for ac3, since I know that .mpg and .mpeg doesn't support ac3, but supports only mp2, mp3 and lpcm. The only mpeg containers that support ac3 are .TS, .M2P, .PS, and .M2TS.

Are the .MPG files imported by Vegas, just .VOB files renamed to .MPG ? Or are they really .MPG ? Are there any problems that can occur while editing mpg files with ac3 audio, in Vegas ?
