Playback of HD-DVD EVO video only (via modified XPL) was much lower, but still 25% higher than for PowerDVD with the same material.
In relation to the above I subsequently conducted a more detailed analysis of the CPU use from individual processes associated with HD-DVD playback and compared TMT to PowerDVD.

The above results were with GPU acceleration enabled (which works) and showrd that while there was an increase in CPU load compared to PowerDVD, the increase in playing the DD+ audio was much greater.

3) Any attempt to go to full screen mode after DVD playback has commenced fails and the program becomes unresponsive. It then needs to be shut down via Windows task manager. It is however possible to play DVD's in full screen mode by first activating full screen and then commencing playback.
In relation to 2 and 3 above I have now tride TMT on a freshly installed Vista operating system and note the following.
2) With HD-DVD playback I now get sound to all 5 channels when 5.1 surround is selected but centre is still mapped to the right. Changing to headphones deliveres a far better result with the centre channel correctly mapped. After watching some HD-DVD content last night front left and front right sound appropriately mapped and the output to the rear two speakers is different to the front. Whether the headphone option is absolutely correct or not, I'm not 100% sure. It does
not deliver the correct sound result for DVD playback.
3) I no longer have this problem on the new Vista install.

The HD-DVD rips work on local drives, or straight from optical media.
(It still can't play DTS-HD though)
It not play Terminator HD-DVD from HDD. I did however play one of the EVO files, but without sound. The audio codec in the corresponding XPL is DTS-HD. Others that have played successfully have had DD+ audio.
