Thanks, I had a feeling I wouldn't be able to get
color OSD to work with the 7300. I would use the grey
one but on standard def the OSD resolution is messed
up so it's hard to read the OSD. I found a work around
though as I setup a match criteria to use standard
ffmpeg at standard def and XvMC at high def so only on
a few channels do I get a grey OSD which is worth it
since the xvmc performs much better. Thanks for the help.
