I can sucessfully receive DVB-T RiksTV channels in Norway using the
latest myth trunk version. Some weeks ago there was no audio using
trunk, but the latest revisions also supports audio.

I scanned for the channels using Full Scan (tuned) using the
frequencies for the closest DVB-T transmitter.

I had the same problems with JYAs VDPAU patches, but after updating to
trunk this worked.
