Video but no audio from mpg

I just bought a new Sony DCR SR200 camcorder and created an mpg file with the optional wireless microphone. Works flawlessly, but the file that's created refuses to import into Vegas 4.0 with both a video and audio track. I can take it home to my Vegas 7.0 and it works fine, but unfortunately at work 4.0 is the best I have. I tried the "change the suffix to .vob" fix, but no luck. I f anyone can help me out it'll save me a whole bunch of work at home...where I'd rather be playing games! Thanks.

Upgrade that PC to the new VMS too. There's not much else you can do other than re-encoding the file.

The chances are that the file has ac3 audio, which older versions of VMS don't support.

You could try installing an ac3 decoder filter e.g. [url=http://ac3filter.net/projects/ac3filter] and see if that helps (although VMS may still block it).

Alternatively, extract the audio to a WAV file using VirtualDub-MPEG2 together with the AC3ACM codec from the same author - get both from [url=http://home.comcast.net/~fcchandler] or [url=http://www.videohelp.com/tools/Virtualdub-MPEG2] and [url=http://www.videohelp.com/tools/AC3_ACM_Decompressor]. Once you've got the audio as a WAV file, drop it on the timeline and group the video and audio together.

"I can take it home to my Vegas 7.0 and it works fine,"

As another alternative workaround, if you don't want additional tools or can't upgrade 4.0: Could you simply export the a/v using version 7.0 at home (maybe to avi so you avoid additional quality loss), then import that into 4.0 at work?

I know it's not pretty, but workarounds seldom are in a pinch.
