Tomcola what burner softw are you using. With Nero I think you need the latest version or at least dwnld their mpeg2 codec. For Roxio Easy CD & DVD it has the codecs built in. As suggested earlier, for Roxio Toast I can just drag & drop the movie files into Toast & it will do any necessary conversions itself. (That includes mpeg1-4, divx & avi files.)
For other things such as joining & splitting
There's also
http://www.videohelp.com/tools which will give you a decent list of utilities. And search options.
As for a help page to show which apps to use & how to do it, well I've seen a couple at least for both mac & windows but I don't have a link for them. I can't remember where I found them. As I said earlier, windows & mac use different apps & I'm not a windows user per se. I know this IS what you're looking for.
I did a quick google & came uup with these links:

Not what I've seen before but it's a start.
