      Hi, just received some cables for my mark iii there and using a koryuu with composite video cables. Basically when I turn on the machine the picture displays totally fine (as good as composite can) but after playing a game for even 30 seconds the sync starts to come in and out with the screen going black and the ossc switching between 256 and 570i it seems. This gets quicker and quicker the longer the console is on until it’s so fast that no picture displays at all. If the console is restarted it takes a few seconds before this starts to happen again. Any ideas what causes this? Bad cables?

        Does the same occur if you plug composite into OSSC Y-input directly?
