Today I tried to install retropie on my pi but connecting it to a crt tv just output blurred black and white pictures while HDMI works just fine; I know it is probably a color (NTSC/PAL/...) problem so as I am using a PAL TV I uncommented sdtv_mode=2 line in config.txt but retropie just seems to ignore my configuration. I tried all the four sdtv modes but no one worked -they all outut the same black and white blurred video buffer; I'm using a Raspberry PI 2 B with a camcorder composite output cable (I swapped the video and right connectors) that worked with ubuntu mate, raspbian and openelec.
Any solution?
