[mythtv-users] MythTV and Widescreen displays?

[vze2hn5x at verizon.net]

Hello,

I recently installed mythtv on my linux system (Source Mage Linux 0.9.3 
if that matters), and I have a question - I have a standard cable tv 
card (4:3 aspect ratio) and a wide-screen monitor (1280x768 screen 
resolution).  When I try to use my tv tuner with xawtv in full-screen 
mode, I get black boarders on the left and right sides of the video.  
When I do the same thing with mythtv using the live tv option, the 
program stretches the video out left and right to fill the entire 
monitor.  I've tried using the w key to switch between different aspect 
ratio's, but the video goes from the left to the right of the monitor 
regardless of which setting I use.  Is there anyway to get mythtv to 
display the tv broadcast correctly?

Thanks,
Eric
