[mythtv-users] Modeline for DVI Output

[Paul Miller]

I'm am very interested in any results you may have.  I have a Radeon 
9700 AIW and I've been considering purchasing a DVI->HDMI cable to 
connect it to my 27" Sony WEGA HDTV.  Have you tried ATI's binary 
driver?  It works fine with kernel 2.6.9 and XFree 4.3 and X.Org 
6.7.0.  There's also a shareware program for Windows to help find the 
modelines.  It called Power-something(?).

Best Buy's only cable is something like $120 and they only have a 15' 
long cable.  I don't want to spend that much.  It's a differential 
digital signal, so I'm sure any respectable quality cable will be 
sufficient, especially for 4-6'.
