I haven’t used Shark codecs as much as I used to since going to 64-bit…since one of the primary reasons was to get MKV playback both on my main HTPC and xbox360 extender. It works great on 32bit Win7, but on 64-bit you have to go into the Shark control panel and check back and forth to get smooth playback on both. I ended up converting my MKVs to M2TS to get around this issue. Lots of options with Shark though, I still would be interested in hearing how people here use it in their setup!
