To be more specific, you need to modify the audio to be 48kHz and make it a DVD-Video with MPEG-1 video stream. SVCDs don't work and I don't recommend doing any experiments, because even in odd case that _your_ player happens to play SVCD-on-DVD-R, it's not any standard and 99% of the players wont play it. Anyway, what you need to do, is this:
-open your VCD-compatible MPEG-1 file and Demux it with TMPGEnc
-use TMPGEnc's audio only (or some MP2 (not MP3) encoder) feature and open the .mp2 file and change its frequency to 48kHz.
-rename the resulting new 48kHz .mp2 to .mpa file. Keep the names of .m1v (the video file) and .mpa file the same (like Video1.m1v and Video1.mpa)
-use SpruceUp to author a new DVD-Video layout and use the files you just generated as an input and create a VIDEO_TS directory
-burn the thing using Nero with UDF/ISO format to DVD-R
geewiz: Of course you need. You can't record music to CD using your tape recorder, can you? Similiar difference, although I admit the discs look the same, but their physical structure is totally different.
