I"ve managed to download and copy the image of 10842 to SD.
Pluging in to my Pi boots fine, but when XBMC launches I"m left running in the top left quarter of my TV.
I"m using an RCA cable to an old CRT 22" which makes it nearly impossible to read any of the text.
Is there a setting menu I can change, or a text file on the SD Card which could be tweaked? If it"s something in a menu, I could really do with a screenshot walkthrough.
I've experienced the same thing using the RCA / Composite output. I believe it is an XBMC bug and not a openelec-specific bug though. Perhaps somebody thats gotten XBMC running on the debian image can confirm whether it works there or not. Though, on the debian image it may be running under X.org, where as on openelec its running standalone, which could make a very big difference.
There are video calibration settings in XBMC that you can use to get it to fill a little over 1/2 the screen, but you can't get it to totally fill.
I had the same (Small Win in corner) when I tried composite, went to System/System/Video Output and Clicked the Display Mode Arrows, the text (Windowed) didn't change but it went full screen and stayed that way accross reboots.
Problem was when I went back to HDMI that was stuck in the corner and setting didn't change it, had to delete guisettings.xml in the end to get it back. Should do it and compare the guisettings files I suppose.
