DivX to DVD does more than just DivX, I believe it can handle Quicktime and Real Media. But you may need Quicktime Alternative and Real Alternative to carry out any conversions from *.MOV and *.RAM to MPEG. (With the aforementioned codecs, any decent encoder, TMPGEnc, for instance, can do the job). And get rid of those bastard players. :Z
Check out the video encoders, tools section, at http://www.videohelp.com
There is a specific converter for *.RAM , IIRC, which could output something DivX to DVD can accept if other methods fail. The app will handle AVIs and MPEGs for certain.
There are also a multitude of tutorials for various tools. You'll find, however, that many of them are quite advanced. Good luck.
[EDIT] Yeah, there are RM converters there. I rarely deal with ASF, but know that some versions of VirtualDub will accept them if all else fails.
