PowerDVD 9 Ultra: Disable 1080p24 While Viewing DVDs?

[Yog-Sothoth]

For BD playback with my HTPC, I use the PowerDVD 9 Ultra plug-in for Windows 7 Media Center. BDs play at the desired 1080p24 (my ATI desktop settings), but DVDs also play at 1080p24. While that works for some DVD movies, most TV shows on DVD look horrendous when forced to 24 fps. Media Center itself outputs at 1080p60 (even though the desktop is set to 24), including DVDs viewed using its built-in DVD player, but PowerDVD with hardware acceleration looks much better to me for DVDs. Does anyone know of a method for the PowerDVD plug-in to automatically switch to 1080p60 while playing DVDs? Thanks in advance.

[EDIT]

I see someone else is annoyed by this:

To watch a blu-ray I have to manually set the refresh rate to 24Hz.

When I'm done I have to set it back (because 24Hz sucks for anything else).
