Yes, thanks. It looks like http://code.mythtv.org/trac/ticket/11442,
fix committed to 0.26-fixes on 7 March,

My apologies for starting the thread without a proper check.

And perhaps I should add that the stock SL6 kernel does work, for me, 
with an older, SD-only usb stick, 704J, although Project-X has always 
seen packets out of sequence from this device and there are often 
noticeable video artefacts.  The HD/SD 290e gives excellent results, but 
needs the extra v4l support.

Only one tuner from the twin-tuner 704J is recognised, with great 
difficulty, by mythtvsetup under the current Fedora 17 kernel, 
3.8.4-102.fc17.x86_64, and results have been poor.  Ticket #11058 etc.
