Using the latest "9u" version under 10.4.3. Selected the "iPod h.264" conversion but increased the bitrate to 450. Used 48kHz/128kbps audio. Source was an AVI (QT identifies it as Divx). When the encoding finishes, the video runs at twice the speed of the audio so, at the halfway point of the file, there's just a white screen for the balance of the audio.
I tried the ".MP4 mpeg-4" setting and the encoding is fine (albeit larger in file size because I had to use a larger frame and higher bitrate to achieve the same quality).
Any ideas? Thanks

Oops! Just read the advice to "decode with QT" when using this setting and that it worked for the poster. Trying it now. Will report here when done in about 40 minutes.

Woo-hoo! The "Decode with QuickTime" checkbox did the trick. The app had a recommended bitrate setting of 197kbps but I bumped it up to 375kbps. Then I tweaked the "Q" settings to min=2 and max=30. Audio was encoded at 128kb@48kHz. The source video was PAL (25fps) and I changed it to 29.97 (NTSC). (I wasn't sure whether 25fps was permitted as the specs at Apple's website say 30fps so that's what I used.) This was a 100 minute movie that, after encoding, is 366MB. The quality in the iPod's screen is superb but, even on the TV (over Apple's iPod AV cable), the quality is excellent with no apparent artifacts.
