[mythtv] UK MHEG working?

[Duncan Brown]

I've been running trunk for the last month and a half or so, up to the rc1

In all versions I've tried, UK interactive doesnt appear to be working. 
On radio stations, nothing comes up.

On BBC or other channels, the 'red button' option appears, but when you 
open it  just the menu backgrounds appear but with no text

Is this a known issue, as I cant see any tickets, or anything in the 
release notes? (saying that, searching for MHEG in trac is difficult at 
best)

cheers
