[mythtv] Audio Sync (Lipsync)

[Andreas Fey]

Hi Folks,

a few weeks ago I bought a new LCD TV and noticed that the audio signal 
is a few milliseconds (200) ahead the picture - which seems to be a 
usual problem with LCD devices. Even more users noticed that problem and 
put it to the wishlist of mythtv. Usual DVD and BluRay Players have a 
feature to set up an audio offset value, AKA lipsync feature, so I 
thoughtit would be a good idea to integrate it into mythtv, too.

Thanks to Marc Randolph, I re-started programming C++ and added a, IMHO, 
nice feature which enables the user to set up a audio sync offset in the 
general settings of mythfrontend (separate for each host). This offset 
is added initially to the audio offset already used transiently during 
playback.

Because this is my first try contributing to mythtv (and getting in 
touch with C++ after years), I just wanted to ask which way would be 
best to let others test these changes (as you might know, I don't have 
write access to SVN ;-)

I attached a patch to this email. I am really looking forward to hear 
from you guys!

Regards,

Andreas
