mpeg2 with audio edit

we record NTSC video with audio to DVD-Rs using Panasonic LQ-MD800P recorders. These are industrial recordings to document work in a really nasty place. We record up to 4 hours to a single sided disk. This is adequate until I'm asked to edit a segment usually a few minutes long. Using Architect, I can bracket a couple of minutes with audio. People walk away happy. But actually editing is not successful at all. Vegas balks but allows the audio with video file to load. The file is visible on the timeline and seems to edit. But the audio envelope while visible will not play back. If you zoom in to look closely at the audio, it disappears all together.

This is not a desperate situation. But, if there is a work around to allow editing of these files, I would like to know what it is. Any ideas or is it hopeless?

ya know the 'import dvd disk' ? It doesn't seem to work for either mpg or VOB files off a hard drive with Vegas 8.0(a) build 176. Was this broken at one time?

Now I'm thinking the problem may be how we record it to DVD to begin with. DVDs play on most machines. Audio and video are in one file. But recording 4 hours to one side means a slow bit stream. Could that be why the Import DVD feature doesn't recognize the files? So we'll try something recorded in a normal way.

so it seems. DVD import works just fine for normal files. The problems stems from the way we record to disk. So now I'm wondering if there's a solution other that retrograde as in recording it back to DV and recapturing. Hey, I've done worse.

And thanks for all the help. You've been great.

DVD- recorders usually use a different structure on the disk compared to normal 'DVD-Video' disks - some disk rippers can't handle it properly.

I've successfully used Nero Vision Express (part of the full Nero suite) in the past to rip movies - to MPEG files - from DVD recorder disks.

If you have capture hardware (canopus or something) you could play the DVD back on a DVD player and capture it.

That's my preferred method for importing DVD material. It seems to be far less troublesome than the import camcorder disc function. I just plain works.

yes but I've decided Nero is evil. At one time it was actually good and gentle software. But the marketing weenies got hold of it and I refuse, refuse to load it on another machine.

I spoke to Spot briefly at WEVA about MPG editing and he said off the cuff, "Of course you can edit MPG in Vegas." without any detail on how to do it.

There are a whole bunch of postings on this with good info if you are willing to plod thought it. And I did learn something by reviewing the past. But nothing has changed. I still can't edit this stuff. And I was feeling so superior since the FCP guy couldn't edit it and I was so sure I could.

No and wasn't sure you could do that in Vegas. Could of course transfer to DV and recapture. Canopus? Guess I better dive more into the past.

That's why I'm still using Nero 7....

Yes, you can edit MPEG in Vegas (V8 even does MPEG smart rendering) but it can be a bit picky about the source files. If you just need simple MPEG editing, Womble MPEG Video Wizard and VideoRedo are faster and more tolerant.
