I'm not familiar off hand with your player, but be warned that some older Sony models don't support SVCD and the only way to make it work is to author the SVCD as a VCD. A guide was recently posted here on doing that. Other older Sony models do support SVCD, but they don't support CD-R media very well. Unless you have a new model that specifically says it supports the format, I suggest burning to CD-RW as that offers you the best chance of success with a Sony DVD player. Follow the SVCD instructions at a place like
