OK, check this out...

This may be a little bit difficult to describe...

I have MCE on my laptop...It has composite and svideo as well as analog inputs for the TV tuner...I can watch TV just fine...Everything is clear, crispy, works great...Sucks that MCE doesn't let me choose between the two without doing a 3 minute song and dance, but whatever...

However, if I plug in my PS2, there is a lag when I press buttons, like maybe up to 2 seconds...As in, if I have the video cable connected, unplug it, the video will show for a couple of seconds before going blank...Same with the audio...

Now the flip shit is, it only does it when I'm trying to use the controller...If I set the game to the demo mode, everything is fine...The commentary, movements...Everything...But if I hit pause on my controller, it takes a couple of seconds before it will respond on screen...

As you may guess, that fucks up gaming quite a bit...The cables are fine as far as I can tell, I hook them up to the TV, and the game played fine...Maybe I need to grab some HQ cables or something...

Anywho, I hope ihs is fairly clear...Any ideas..?

Yep, that's all normal. MCE buffers TV output by 2-3 seconds, making teal time interaction with the signal impossible. If you want to use your tuner to play games, you'll need to use a different app that doesn't buffer the signal (i.e. a non-DVR tuner app).

Yup, you're right...Somebody on my site pointed me in the direction of ChrisTV, and I've been playing games ever since...
