Hi kszaq:
I just want to double check -- I was using mythtv addon, trying to stream the NFL network TV channel. So it appears to me that the issue is the hardware decoding (GPU) was somehow not enabled/used properly in the latest version, so that all of the video decoding was carried out by all 4 of the CPU cores. (Whereas with the earlier 8.0.2 image, the GPU was in use and works really well).
Please let me know if you still think I should start a new thread & I'd be happy to.
Thanks!
