Just one comment on GPU support. GPU does not help in this case. It is the DSP that is accelerating the decoding. The DSP is a TI C64x. The resolution is intentionaly clamped at around the display size as the dsp is not fast enough to do higher resolutions. Also please be aware that the DSP cannot accelerate all of H264 Main and High profile.

Just as an update, decoding of .ts MPEG2 transport streams still fails. (At least when accessed in the Media Player over DLNA, haven't tested if it works when I copy the file over.)
