Thanks for trying to keep up the MPC development Casimir
Are you guys doing anything special to use EVR in XP ?
I'm currently using Windows XP x64 and the EVR option is greyed out for me
I'm also finding that the "left click to pause" does not always work and sometimes rewinds the video and plays from the beginning
[edit]
Could some kind soul using Vista see if the EVR option stops the screensaver or powersave options from kicking in while media is playing please?
I'd try it myself in Vista, but I only have a slimmed XP 64 installed at the mo while I'm testing some memory
