He claims he's using the last public JIT version of OWB.
Can you confirm the video acts the same in your case?
It absolutely does not. I only see 360P as an option on MorphOS.
I tested the same video with leopard-webkit on MacOS 10.5 (PowerPC) and was able to play in 720P.
Based on what I was able to quickly research, Google are using AAC or AAC+ to encode audio for higher quality versions of H.264/MP4 YouTube videos. (360P versions use plain 128kbps MP3 audio.) For older YouTube videos, 720P versions might also use different audio codecs so it can happen that some older video files work in higher resolutions but newer ones do not.
AAC / AAC+ is likely not an issue even on older versions of MacOS as leopard-webkit utilizes Apple's Quicktime codecs.
As for zukow, as he mentions on PPA that the video runs slow for him, it is possible that YouTube is playing the VP8 version, which uses Opus rather than AAC / AAC+. This would explain the difference in behaviour (h.264 vs VP8).
I did a quick test and while a plain AAC audio file appeared to play fine, Odyssey did not play an AAC+ (also referred to as "HE-AAC") audio file. Perhaps this is the issue right there.
