Is demultiplexing/remultiplexing needed for FF/RW

[lemmy999]

I know some players have problems if you use NERO to burn a TMPGEnc encoded MPEG2 to SVCD because there are no scan offsets. This will cause them not to FF/RW. So I have always encoded with TMPGEnc, demultiplexed with TMPGEnc, then multiplexed with bbMPEG, then made an image with VCDImager 0.7.7. If I just enabled the "update scan offsets" in VCDIMager, do I really need to do the demux/mux steps?

I don't think you need to demux/remux. After I use VCDImager 0.7.9 (with update scan offsets option on, of course) now I'm able to FF/RW and use Goto function on my SVCD. VCDImager seems to fix on the problem with FF/RW completely, thanks to hvr.

thanks. this is what i have noticed. i have tried both ways and both work fine in my player. i had heard some players were more sensitive about the scandata than others were. i have performed vcddebug on both .bin files (one created from a tmpgenc file w/ update scan offsets and the other from a demux/remux from bbmpeg) and the only difference i see in the output is the movie file on the svcd on the bbmpeg file is slightly larger (around 6000kb). I wonder what extra data bbmpeg is placing in the file?
