Yesterday I popped in a couple of games and here's what happened:
- Super Street Fighter II X and Vampire Chronicle:
The screen only showed the upper-left quarter of game in full screen. (In other words, the game was displayed 4-times larger than it shoud be)
- Giga Wing and SF Zero 3:
The DC was not able to boot the games at all.
Now, when I switched the cable to "AV" the games suddenly worked without a problem, but obviously I don't want to play them in AV.

Strangely, I only have this problem with some Capcom games, all other games work fine.

Can somebody tell me what the fuck is going on? Do some games just not support RGB!?
