[mythtv-users] GL problem in Mythfrontend after Firefox/ BBC iPlayer crash

[John Pilkington]

I've been playing with BBC iPlayer (which has worked) and the BBC 
iPlayer Desktop, which hasn't worked for me although it is installed and 
seems to run.  At present Firefox crashes at the end of the iPlayer home 
page.  The BBC systems use Adobe Flash and Adobe AIR, and the content is 
supposedly available only within the UK.

Apparently as a result of this, the main Mythfrontend menu is blank but 
the menu choices still work and submenus are visible.  When the blank 
menu page is visible the frontend log repeats indefinitely:

   QGLContext::makeCurrent(): Cannot make invalid context current

Rebooting didn't resolve this.

Using another Mythbox as a guide I was able to step through the menus to 
select Qt instead of Open GL. Reselecting OpenGL produced a usable 
system again, but I'll probably use Qt until the other problems are 
resolved.

Have other people had success with the BBC/Adobe systems on a 64-bit 
system (mine is FC10 with Yeechang's modified 0.21 fixes), and, more 
urgently, can anyone suggest a less cumbersome way of recovering from 
the QGL 'invalid context'?  Changing the OpenGL Settings in the nVidia 
utility didn't help.

TIA
