Hi,
I have quite a few mpeg 1 files, and mpeg 2 files which I would like to join into larger files (no larger than 2gb though). Note, I don't want to join mpeg 1 to mpeg2, just mpeg1 to mpeg1 and mpeg2 to mpeg2.
My question is does VS9 do this without re-encoding? If so, how should I save the joined files? As "same as project settings" or "same as first video clip"? I realise that if I edit them, it will re-encode at the cut points, but if I don't edit them, my feeling is, they should stay in their original form without any loss of quality. Am I correct?
If VS9 can join without re-encoding, then I won't have to go out an buy specialised mpeg joiner, though I guess if I want to edit them then I might have to invest in womble or videoredo or the like.
thanks
joining mpeg1s and mpeg2s without re-encoding

Were the videos made using the same properties? Like all the mpeg1's have the same properties, and all the mpeg2's have the same properties?
What happens if you just try a quick test -- put them in a project and output with smart render
If you have to do edits, then the two apps you mentioned have a good reputation (I've never used them though).

Yes, all the mpeg1 files I want to join have the same properties, and so do the mpeg 2 files I want to join. In this case, if I just join files having the same properties, will VS9 doing any re-encoding, and thus (further) diminish video quality. I know womble and videoredo can join without re-encoding, but can VS9?
It seems to work fine for both mpeg 1 and mpeg 2. That is, they seem to join without much or any degradation of quality. Also the creation of the file, in "same as project properties" is pretty quick, all of which leads me to think that there is either no, or very little re-encoding. Am I correct, or am I missing something?
I don't think you are missing anything 
Just watch for "audio drift" in long video combinations -- not that you will have any, just something to keep in mind (I think that's where those programs you mentioned really shine -- ability to slice/dice mpegs and maintain audio/video sync).
btw, if you don't do any edits, you might be able to just Author a DVD with the different files (depends on how long they are, and if you don't mind a little "pause" between titles on the DVD -- fade to/from black usually masks the "pause" between Titles on a DVD during playback).
