MythTV uses VDPAU to talk to Nvidia GPUs and VAAPI to talk to Intel GPUs. VAAPI has been updated, as Gary mentioned, to take advantage of improved Intel GPU deinterlacers. The MythTV frontend code needs to be updated to take advantage of the VAAPI updates.

It is not clear to me if the ECS Liva has some of those GPU deinterlacer improvements.
