bluray Wrote:i'm not sure what is lanczos3. you can try set onkyo 608 to passthrough video and turn off dxva2 to see if it can playback fluently.
i don't use anything special in one of my htpc other than ati radeon hd 6570 and another htpc with gt 430. it's crystal clear as bluray playback using ps3.
LANCZOS 3 is a video decoding setting inside XBMC if you do not use DXVA you can select which decoding you like in the settings whilst playing a movie.. I find that this filter or codec whatever you call it
has the best quality in playback with HD Movies .. its crystal clear and you can see all the pores on peoples faces whilst when I enable DXVA2 in XBMC I have flawlass DTS HD MA audio but the video is alot more smooth and not as sharp as Lanczos 3 setting also my blacks are more medium grey
Do you think I need to tweakl my ATI card settings or is that just the way DXVA2 works?
Also I see on your previous thread you state that in windows the speaker configuration for the ATI sound card should be set to 2.0 (stereo) instead of 5.1.. whats the reason for this? Do you think that may be the reason the sound is choppey whilst playing DTS HD MA or DD TRUE HD whilst not using DXVA2 ? Thanks
