Try rendering to mpeg2 thith the adobe media encoder in the export settings in Premier Pro I use CS3 but CS2 has it to I don’t know if the previous versions have It, The setting I would suggest
Format: mpeg2-dvd
Quality: 5
Bitrate Encoding: VBR, 2 pass
in the multiplexer select DVD that will put the audio and video in one file.
VOB files are basically mpeg2’s
Hope this helps
