[AG-TECH] HD on AG

[Gurcharan S. Khanna]

Doug,

I'm trying out the ucl vic you modified to render 1920x1080. I'm looking 
at it via VNC so it's
limited but when i'm getting looks like standard definition in terms of 
resolution (720x480)
no matter what codec (mp4, h264, 261as) i use and no matter what the 
size is set to (small,
med, large).

any thoughts?

thanks,

-gurcharan

PS for devices i get NTSC, 720, and 1080. i also get 59.95 for the frame 
rate from the HDMI
card. (i get this with ultragrid, too). any idea why? instead of 29.9? -gsk
