try to change the refreshrate after it came up like this.
You can do the rest alone, I am sure.
so... out of curiosity i installed a cheap discrete Radeon HD6450 card (based on Caicos chip) and completely disabled the SUMO integrated graphics from my APU. that immediately fixed both problems i was having (one of which i erroneously thought was caused by my TV).
1) first problem was of course the TV detection issue you helped me with the other day. now i'm able to power on the PC and TV in whatever order and i always get a working video output. no "no signal" and no corrupted image.
2) with the integrated SUMO graphic i was getting some severe jerkiness (not sure how to call it: it was like some severe framerate drops that lasted 5 seconds or so and repeated regularly, despite codecinfo window never showing anything wrong) when playing my own 23.976 fps encoded blu-ray rips at 23.97608 Hz (confirmed by xbmc-xrandr). i had to force a 24.0000 Hz output through advancedsettings.xml for 23.976 fps encoded videos otherwise they were totally unwatchable. this after trying every possible setting combination inside XBMC.
i thought it was caused by my TV but now, using the HD6450, they play just fine at 23.97608 Hz (according to xbmc-xrandr)... smoooooth and all.
could these be considered bugs in the radeon driver specific to the SUMO platform? i would report them but i'm not sure where and more importantly what kind of log to provide, especially for the second one.
