no audio, no pic after burning dvd-r pls help

Now that i have solve half my problems, theres the next batch to come, so sorry.
to troubleshoot some more. theres no sound coming
out, i know the sound is AC3 Audio (192 kbp/s) that was demux by vobedit v0.6, and later multiplexed back with ifoedit.the conversion with tmpgenc was done to create 2 separate output mv2 + wav.
i used Srt2Sup to
convert a downloaded .srt to .sup and used ifoedit
to put it together, i'm assuming the little box with an ellipsis to the right of subpicture is for opening the source file for the .sup in ifoedit.
but the strange thing is when the movie plays on my home dvd, the subtitles can't be seen, however you can actually see the background of the subs in black, but no words.So it's just a black boxed background appearing everytime they speak with no text.
I'm using win XP, and i heard that you run into problems when using ifoedit, if this is true, is there another program out there to multiplex. I'm stuck and don't know what to do, pls help.
