I've been experimenting with a lot of codecs over the years, and belive I have found the best ones. I could need a bit of pointers of wich order to install them in, and maby some hidden dangers along the way. So, this is my plan:
Dscaler5: DVD's
CoreAVC: MKV and HD material (really the only thing for playback of 1080P as I know of)
Quick Alternative: Quicktime files
Real Alternative: Real something
CCCP: For playback of every other video format
AC3 Filter: Sound
My current plan is to install all of this, in this order. That way I might just have to change playback decoder to CoreAVC for the MKV files. I have an almost identical setup today, but the sound was screwed up. Stereo was ok, but the voices (front speaker) of surround was terriby low (DVD and HD material). After a lot of audio decoder changes the 1080P video content started skipping again. Just like using bad video decoders. That's why I have to revert to an older image and start over. I don't know. Maby I should leave out the AC3 and don't mess with the sound settings at all.
The hard part here seems to be to get a perfect picture (no skipping) on 1080P content as well as a good sound setup for 5.1 and 7.1 source. Any suggestions are welcome.
