I've been using a PC to play XviD's and watch DigiTV recordings etc on my plasma for a while now, but have just bought a SweetSpot and have been been playing with PowerStrip some more. So I have successfully "snapped in" (1:1 pixel match) my HTPC (radeon 9200 gfx) with my Plasma at 50Hz (for PAL), 59.94Hz (for NTSC video) and 72Hz (for NTSC film) and they work great. My next plan was to create 3 display profiles in PowerStrip to easily switch between these refresh rates. However, no matter what I do the refresh rate does not change when I choose a new profile! This is driving me mad - what am I doing wrong - or can't I do this with PowerStrip? Thanks in advance. Rob.
