What is the best way to Convert smil (real media) files?

[EWT]

I have a group of real media files: smil, rm, and rp:

The smil is a text file which calls up the other two files when played on my media player classic.

One of those two called up in the .smil text file is an .rm file which is strictly audio narration (no video). The other file paired up with the .rm audio file is an .rp file which is a text file. The .rp file does nothing more than call up a bunch of .jpg slides in the same folder. The .rp text file contains timing and sequencing info so that it syncs up with the audio narration.

I would like to convert this to .avi or .mp4 on my hard drive for further processing (ultimately making a DVD that will play in the majority of home type dvd players; not computer dvd drives). Am I stuck with doing a video screen capture or is there an easier way to go about doing this, seeing that I have 50 to 60 different sets of this typ of presentation that I need to do?

Thanks in advance for any help offered.
