I have been happily using DVD2SVCD for about a year and a half. I have successfully made many SVCDs and then, since my standalone Sony DVD player won't play SVCDs, have used the "VCD header trick" to multiplex the muxed files and have burned a dozen or more VCDs which work very well in the Sony. My problems started several months ago when I began getting problems with the burned VCDs being out of synch on Sony - while working fine on my PC. I have searched through posts on this board and on Doom's board and can't find anything which helps me to resolve this problem. During the period leading up to the problem, I updated DVD2SVCD to ver 1.1.0 b1 (but am still using the original CCE 2.50), updated Nero Burning to ver 5.5.10 but went back to ver 5.5.9.17 after reading about problems with the newer version. Somewhere along the line I have acquired a mixed ASPI layer ( I have no idea if this is related to the problem)with the following: ASPI32.SYS- ver 4.7 WOWPOST.EXE - ver 4.6 1021) WINASPI.DLL - ver 4.6(1021) WNASPI32.DLL -ver 4.7. I've been perplexed by this for nearly two months now and can't figure out why even though the "header tricked" files appear fine on my PC they keep being out of synch when I burn them. Can someone please help!
