Hi Aaron407,

We're trying to amalgamate all the Sony BDP, Sony HT and Sony SMP device profiles together so they are less confusing for users and easier to maintain for us. So, we'd like you to continue to use the Sony BDP, HT, SMP device profile. If there are any issues with it (like the MKV problem), then it tells us that we have to tweak it slightly. Contact us and we'll send our the new device profile for testing.
