I successfully burned an AVI with SRT subtitles to SVCD using TMPGEnc on a PC. But it had to be split accross four CD-Rs. I'd like to stick it all on one DVD instead but the only access to a DVD burner I have is on a Mac. How can I convert the AVI and SRT to be burned on DVD using iDVD?

I used TMPGEnc to output 5 minutes of it for DVD in MPEG-2 as a test but, as I understand it, that format can't be read on a Mac without purchasing a plugin.

TIA
