[Q] How to alter the color of subtitles in Vista MCE, who controls what?.

I have two Vista boxes one connected to a PC and one to a 57" Sony TV via
DVI. Subtitles for a DVD on the PC have a nice black outline around yellow
letters making it much easier to read vs on the TV where the black outline
doesn't show, just the yellow making it very difficult/impossible on a light
or white background.

Where is this controlled? How is the DVD displaying its subtitles
differently on the output devices? BTW - both systems are using ATI
Catalyst 7.3, but different ATI cards. Thanks -

PS - Also is there a reg. setting like Tweak MCE2005 to alter the amount of
time menus remain on the screen after clicking? Tweak MCE2005 let you set
the interval in milliseconds [?] so they could go away more quickly if
desired.
