Honestly, we were taken aback when Toshiba released version 3.0 firmware for its launch HD DVD players two years after release, but that has been replaced by absolute shock, at a 4.0 software update for the long-dead format. The whole family can join in on this one, either via the player or downloading and burning a copy from the website, with updates available for the whole line: HD-A1, HD-XA1, HD-D1, HD-A35, HD-A2, HD-A2W, HD-A2C, HD-D2, HD-A20, HD-XA2, HD-A3, HD-D3, HD-A30. The only official word is this patch "addresses certain playback issues" -- forum posters report 1080p/24 playback jaggies on MPEG-4 AVC-encoded titles like Transformers is no longer a problem. If everything is working fine (and, of course, you're still using your HD DVD player) it may be best to wait until more reports to avoid any potential compatibility problems.
