No PAFF, good Sir. Perhaps you or your buddies can contribute to the cause?

Also I transmuxed a 1080p H.264 from HD-DVD (not personally, but I had a 115MB ISO). Played fine for about 28 seconds but then started to stutter and lost audio. I didn't see any obvious reason, so I assumed it was bitrate.
Said encode is here:

Don't pay attention to the audio bitrates, I simply encoded at -q 0.3 to give me a similar filesize to the AC3.

No luck with Bluray, the tools I have reported no startcode, so perhaps Bluray fucks it up, or I've just got a bad sample. However I wouldn't rule out Bluray fucking stuff up, just because Sony has some involvement with Bluray.

I'd really appreciate a load of different 720p samples/fansubs/AMVs/whatever right now. I have no complaints about SD encodes, it's great, but now it's time to move on and test systematically rather than trying random encodes and wondering why it does/doesn't play correctly. I have a suspicion that 720p support may be borderline. We know it plays SD, and partially plays 1080p. It can get away with 1080i H.264 (which I assume uses pretty relaxed encoding settings being for broadcast); but I want to see where it stands with 720p, since it's quite easy to reach level 5 just by using 16 reference frames on a 720p encode.

/me refused himself to use Main Profile when asked to encode to spec *tongue out*
I think he probably means the MP4 container and it's awareness/support in general. Also I believe iPod is Baseline @ 1.3, but newer models may be more capable (but I expect them to still be Baseline).

And yeah, I won't cripple my encodes for Apple's half hearted decoder, if they want to become a player in the media market (pun not intended), they need to get their finger out and start with the High Profile support (in iTunes at the very least, and do something about AppleTV before it gives standalone players a bad name (with what it supports, it may as well not support H.264 at all).
