Hey bads, Have had a couple that I've gotten same way> Extract the dat files to HD. Change DAT to MPG. Will play just fine.
AVSEQ01.DAT .> AVSEQ01.mpg
AVSEQ02.DAT > AVSEQ02.mpg ect
What I don't understand is svcd usually leaves them as an mpg while vcd changes them to dat file.
Also if you try to combine the files to 1 big file will get out of sync
when burnt to disk as VCD will change mpg file to DAT file. Use ISOBuster or choice and extract dat file to had as a mpg file. If files already on the drive, most of the time, can change extension.
