Thank you mate going to test

-On a CD, maximum bitrate for video files is ~1.4mbps

This is max speed so bitrate of the gdrom drive can handle not talking gdemu

Filesize increased quite a bit and ffprobe now says the the length is 40s instead of 10s, but I think it will play OK on the Dreamcast. This is one weird-ass codec.

Maybe we need to add Joliet filesystem to the script? It's just ISO right now. Also, file 4XM.pvr 'pvr' is lower case. I bet you used Bootdreams to make the CDR's that worked.

MENU.CFG is using lowercase extension in the text.
