Well, you could copy the MPEG-PS to your hard drive with something like vobcopy, using cat to piece the vob files together, then extract the M2V stream with extract_mpeg2, export that to a series of still frames with "transcode -y im -F png" and hand-paint the trails out of each frame with the GIMP, then pipe png2yuv through mpeg2enc to make a new M2V stream, extract the original AC3 stream from your MPEG program stream, multiplex the AC3 and M2V streams together with mplex, use dvdauthor to set up the DVD file system, and burn it with growisofs or whatever your favorite DVD burning program is.

Kind of a lot of work, though.
