@droitwichgas,
Thanks for tip about HUA. No, not tried that yet.
Watching things streamed is "ok" - yeah I don't need to o/c, though it's a bit better at 850MHz cf 600. I was hoping for a higher res, which I could pipe out to a TV if I wanted. Streaming only works with the 396kbps version, where as normal video playbackshould be fine at double that.
From what you say, it seems like you haven't tried get_iplayer, is that correct? Can you play mp4 h264 files?
