This method doesn't work in my player. MPEG2 muxed as SVCD is OK, MPEG2 muxed as VCD is OK, but MPEG1 is only OK if 352x240, or if it's 29.97fps. Then it works both muxed as VCD or SVCD (I like to mux as SVCD because I can put subs and dual audio). If it's at a resolution bigger than 352x240, and it's not 29.97fps, the only way it works is MPEG2. With Mpeg1 the video is smooth but the audio cuts in and out.
I've also tried applying "pulldown" to a MPEG1 stream and muxing as SVCD, and the audio is then OK, but the video is no longer smooth
