I need some help compiling 3 svcd discs onto a DVD-R to play on my stand alone player.

I've tried using the guide provided on this site but after my first attempt, I just need a few adjustments.

Ive demultiplexed all 3 discs using TMPGE, then converted the audio to 48khz using SSRC, In the guide it then says to rename the audio files to .mpa (sounds daft but when I do it the file reads avseq1.mpa.mp2)

I then patch the video using DVD patcher and then onto the MAESTRO stuff. on my last attempt the DVD played the first 1/3 ok with sound, but then as soon as say the 2nd disc would kick in the osund vanished.

Please can anyone point me in the right direction to cure this and also any tips to keep the audio in sync as i've noticed the the sound files are all 2secs longer than the video files ??

Many thanks
