Suddenly, and for the next two weeks, I have a source of HD264 SD in the 
BBC's Red Button Olympic channels, but so far I've only used it on a 
laptop running pre-Qt5 master under 32-bit SL6.  On that, mythtranscode 
--avf worked fine.  I haven't tried it on H264 HD - at least not 
recently - but can easily do so.  Would need to examine the code to see 
how it related to Warpme's report, and that wouldn't be straightforward.

I will try it later with *buntu trusty ppa build, on another laptop, but 
have never recompiled that, so it's presumably close to what you have.

Just now I need to do something else...  :-)
