Just a test of AVCHD @ 1920x1080 on the Sony DSC-TX7. Windows Media Player wouldn’t even play it, and Picasa used Divx Plus to play it, which I thought was weird since Media Player didn’t have trouble playing the AVCHD @1440 x 1080. Even weirder, the software that ships with the camera didn’t have any trouble playing the video as long as I did not try to view it in full screen.
As for processing time when submitting to Youtube, there was a small delay, but it could easily be blamed on additional traffic due to Life in A Day. The actual processing part of the upload actually took a few seconds.
Add to that maybe 5-10 more minutes before the HD streams became available.
