[mythtv] help: segmentation fault with DVB-T

[Matthew Carnevale]

Turns out it was the font files after all.  Those two .ttf files that go 
into /usr/share/myth were corrupt.  Unfortunately my Linux box isn't on 
the 'net, so I have to do all my checkouts / updates from my Windows 
machine, which insists on treating all files as textfiles on the initial 
checkout and converts them to DOS style CR-LF.  I'd written a script 
that converts all the filesi n the tree back to Unix friendly versions 
but it was processing files it shouldn't have. 

Now Myth is working great, I have all the DVB-T channels working, seems 
to have some synchronisation problems (the video plays too slow but the 
audio runs at full speed) on some channels (those wihere the backend 
reports a video bitrate of 10Mbps or above), even though top shows it is 
only using around 25% CPU.  Tried the 'Experimental A/V Code', 'Jitter 
Reduction' and 'Extra Audio Buffering' settings in different 
combinations with varying success. 

One suggestion (unfortunately I don't have the expertise yet to 
contribute this one myself) would be auto pan&scan detection.  Stations 
in my area broadcast in 16:9 aspect all the time and just put black 
borders around the 4:3 content, while some widescreen stuff isn't 
'quite' widescreen so needs to be zoomed.  Maybe mythtv could detect 
these black borders and switch modes automatically.... would be useful 
on normal 4:3 TVs. 

Cheers,

Matt
