Of cause, it's enabled. But as far as i understand it doesn't work for SD content. In settings, when I enable hw decoding, for every codec there are two options: "Never" and "HD and UP"
T2 tuner works like a charm. But I've got a problem with Kodi. Playing T2 channels in SD quality puts CPU on very high load. Even without deinterlacing and bilinear zooming, CPU load reaches 80%, so box overheating begins in 10 minutes.
TVheadend uses only 5-7%, so when i connect to it with external device there are no problems.
