I've finally managed to get my GeCube HD 2600Pro AGP to work with hardware accelaration when viewing BBC HD using DVBViewer.
I'm using the CCC 7.10, Power DVD Ultra 7.3.3516 and AC3Filter V1.46. I also used some registry hacks that I found on the AVSforum 2xxx thread (ATI_HD2x00_Reg_Tweaks_0.6.vbs).
When watching live BBC HD my CPU is barley reading anything 0.8 to 1 % (according to Speedfan) and the GPU goes anywhere from 33 to 60% (according to CCC overclocking tab). I only had to tick the DXVA tab in 'View' / 'filters' within DVBViewer.
Only minor issue is that during BBC HD Preview (when there is frequent changes of video/film clips) the picture goes into a judder like there is only half frame speed. To fix this I have to select 'Rebuild graph' and it's OK for sometime. If I'm watching a single program then it seems to be fine, I guess due to the fact that the type of video/film remains the same during the program.
I have been able to watch recordings using DVBViewer/CoreAVC (no HA)/ACFilter and an older version of CCC, but live viewing wouldn't work with the 2600Pro, so this is a bit of a breakthrough (especially as I now have a 1080p TV to view it on).
Lets hope we can receive Ch4 HD in the future once their tie in with Sky finishes, then I'll have two free HD channels.....
Also I'm thinking of adding this Toshiba HD DVD drive in the new year so I can be dual HD format. If the Power DVD codec is working with HA in DVBViewer, is it logical to assume it will work with HA when using Power DVD to play a HD DVD?
