"Video Error", Live TV, MKV help

[danbruski]

Good afternoon,

Problem:
Some Bluray ripped matroska files like Cars and StarWars have full surround sound, but other matroska files and all other formats only have 2.1

They all used to work in 5.1

Other info:
In Windows Control Planel, I have my AVR as the default and setup as stereo. In WMC, I have it setup for my 5.1 system. I get surround on live tv and also when WMC start-up tones.
Media Control works and the FFDshow and Hali splitter icons show up in the tray but when I ask Media Contol to check sound setup, it shows that "speakers" is selected, not my AVR. I click the AVR option, and it says WMC needs to be restarted, but after it restarts it always goes back to "speaker" instead of my AVR. Is that the cause of the problem, or a symptom, or just unrelated?

Background: I had Shark007 going and you helped me with some settings. My system still wasn't operating as it should, so i uninstalled Shark, Media Control, etc and tried to start over. I get a bit confused by all the formats, codecs, splitters, etc... So i thought i'd start simple, so i installed just the ffdshow tryouts (the version that was new at the time, about 1 month ago) and the splitters suggested in some of the "ffdshow for minamalists" and everything seemed to work great.

Live tv
mkv
mp4

Then something changed, but i don't know what. Maybe some windows update or something. I also tried to put on some post processing and deinterlacing processes which seemed to break the playback. I think i put all those back (turned everything off), but sometime after that I only get surround sound on some movies.

It's frustrating because everything works but the 5.1, if something was broke or not playing, id have a better idea what to change, but this is confusing to me.

My AVR can't handle the HD audio. I have passthru for DTS and AAC (i think that's what it's called).

Even though I don't have Shark007 installed right now, I was hoping you could assist in helping me setup ffdshow and the splitters and the windows sound control to get my surround going. i'll deposit a few more $$ again.

Thanks a lot.
