Following two problems with streaming to a Sony KDL-40V5800:
- Most MKVs won't play, in the sense that I only see a black screen with some purple artifacts in the lower right corner, however, I do hear the soundtrack. There is the rare MKV which does actually play like it's supposed to.
- When searching through the list of available movies on the TV, I'm seeing only MKV files. Every folder which should contain an AVI is empty.

Streaming to a different device (Windows Media Player on a tablet) works just fine and I can see all files.
