That's not the point...it should work, and doesn't. I'm not here to argue codecs :x Also, not only using mkv.

The point is the need to figure out what exactly is broken. Containers, CODECs, and soundtracks all mix together. One person's MKV isn't the same as another's etc. A video container (MKV, MP4, AVI) can contain all sorts of weirdness in it which is why folks want logs and samples of broken stuff. What's in your VC-1 container may not match up with what a developer tests with so he calls it done while you still think it's broken. The more concise the information provided the quicker it can be figured out is all.

Speaking of containers - has anyone got any ideas for how best to catalog a collection to determine what's in it? I mean from the standpoint of X MKV with DTS, X MKV with THD, catalog the bitrates, the containers, things like that. I have a fairly extensive collection of video that should be almost all x.264 encoded but bitrates may vary a little and I know I have everything from AC3 to DTS to THD to even some FLAC as I've varied how I've processed my media over the years. For the purposes of testing it would be really nice if I could see what directory has what but I'll be danged if I'm clear on how best to do a recursive drill down through my collection to catalog this best and would appreciate any ideas!
