Strange error message - win xp

i’m able to burn svcd with nero 6 ultra, but only with m2v files i download. when i try to encode files with tmpgenc plus, it seems like they are svcd compliant, but i get an error messages that say “can’t connect trf” and “not enough memory” when i try to burn. i have plenty of ram and hard drive space, and i only get this message with files encoded with tmpgenc. can anyone help?

never mind, i figured it out. i have to encode with vbr.

now i’m having the problem again. does anyone know what trf is?
