I don't normally run mythbuntu here (or for that matter ubuntu), so a 
test like this may be a while.

No, HVR-1950 support began around roughly the 2.6.26 kernel timeframe.  
That's when it started working here.  But IIRC, HVR-1950 support also 
required updated tuner support in the V4L core and that was still shakey 
arounnd 2.6.26 - but even that stabilized LONG before the 3.x kernel 
series started.

Right now, aside from the FM radio, the HVR-1950 (and presumably the 
HVR-1900) should be working as well as the older PVR-USB2 models, on all 
recent kernel versions.

When you are swapping mythbuntu versions, are you using the same 
firmware files?  Maybe 10.04 is missing the firmware image for the 
HVR-1950's FX2 microcontroller?

I wouldn't be surprised if that were the case.  Mythtv is complex and 
difficult to keep healthy.  Don't get me started there...
