Yeah, actually, my above approach--link called udevinfo--won't work.  
You'd need a script called udevinfo that does a udevadm info "$@" .  
(Realized that after sending.)  So you could upgrade udev, again, if you 
like.

We already have a couple of tickets about the program switch:

http://svn.mythtv.org/trac/ticket/6137
http://svn.mythtv.org/trac/ticket/6866

Before commenting on them or opening a new one for the frontend's 
hanging, it would be wonderul if you could do some testing to try to 
figure out why it only hangs for some people?  The only thing I can 
think of is that maybe those for whom it hangs have "Monitor CD/DVD (and 
other removable devices)" enabled and those for whom it doesn't hang 
don't.  Any information you could provide about what's causing the hang 
would be appreciated.

Also, when starting up and it seems to hang, does Esc make it start 
working again?  (Or several Escapes possibly followed by the exit key 
you've set (Alt+Esc or Ctrl+Esc or Esc or whatever)?

Thanks,
Mike
