Here's where I'm at so far in trying to get this to work:

I can get 540p working using the 540p Modeline from that link you supplied.  
It won't let me use bob deinterlaceing however.  I get this:

2007-07-29 21:54:55.895 Video sync method can't support double framerate 
(refresh rate too low for bob deint)

This, by the way has always been the case with my 1080i mode as well...I've 
always used kernel deinterlace.  To be honest, my existing 1080i seems to 
look better than that 540p mode does.

If I use the 540pw Modeline from that link, it allows me to use bob but I 
have another issue:  When I watch TV the picture is compressed into the 
middle 50% of the screen with wide black bars to the left and right.

Any idea what might cause either of those?  Thanks.

Tom
