Nero Showtime plays most DVDs with no problem. However when I attempt to play a DVD created with PremierePro1.5, Showtime playback creeps very slowly, almost hangs. Try to play with WMP - same result, but if I disable (rename) *only the Nero audio codec* (NeAudio.ax), the video track plays perfectly in WMP (without sound). Showtime of course fails with one of its codecs disabled. Playing Premiere DVDs with WinDVD4 and there is no problem (I assume it uses different codecs).

So this appears to be a problem with Showtime's audio codec when playing Premiere DVDs. I would like Showtime to work as otherwise it's a good program. Any suggestions?
