Reversing header Trick

[Timster]

I have a bunch of video CDs that are actually mpeg2s using the vcd header trick. If I buy a DVD player in the future that only supports SVCD or won't play VCDs using the header trick, is there a way I can rip my .dat files from my VCDS and then reburn them as SVCDs? I've tried the tools in TMPGenc but I keep getting bufffer underflow errors and a 795mb file ends up at only 713mb so somethings wrong. Any help or guides would be appreciated. I'm downloading ISObuster as I write so maybe that will do the trick (or should I say undo).
Thanks,
Tim

Anyone?

Got it figured out. I just needed to de-multiplex and then re-multiplex as SuperVCD. Then burn as a SVCD in VCDeasy. Just glad to know I could do it. Seems I can do the same thing if I upgrade to a DVD-R in the future though I would need to resample the audio to 48k. I'm just glad to know all the VCDs using header trick are not wasted and can be used in the future without re-encoding. There should be a guide for this but I didn't see one.
