I've created a photo slideshow DVD-R from the slideshow software Memories On TV (v2.14) using a LPCM soundtrack. I used the TMPG option to do the encoding and have tried burning from within MOTV and from TMPGenc DVD Author. It plays back fine on my DVD ROM, Pioneer 717 and Pan E100 DVD players but when I play it back on my X-Box (and my sister's) it plays at a faster speed sounding like a Helium inhalation! It sounds like it's playing at the write speed (x2.3) DVD-Rs authored in other software playback fine on the x-box but they have AC3 soundtracks. This is the first that I have done with LPCM. Why does it playback OK on other players but fast on the x-box?
