Weelll I didn't actually solve the problem. I need to play over VLC Media Player right now , and it tends to lag a bit + I need to record all my stunts using fraps so it laggs even more I'll need to buy a composite cable (the one DC has) to be able to use the programm which came with the capture card.
If you want to play with VLC just click on file -> Open some thing which is able to record stuff from the TV (don't know what the heck's the word called in english )
And StormyWormy : The quality is great actually , max. 756x540 (or something like that) resolution though. If you want more you'll need to buy a muuuuuuuuuuuuucchhh more expensive capture card , but yeah I'd say it's alright for console videos .
