Okay i have got my home theater up and running but i got a problem with my sub. Iam using a yamaha rxv-730 reciever with a JBL PB10 sub but when Iam using it in something that isnt DD the sub doesnt kick in. Why is this? When I play xbox it goes but gamecube nothing. Any ideas?

Try this link for some tips on setting up your sub properly.

I think more info is needed to really help you out:
* How is the sub connected to the Receiver (Speaker or line level out?
* What are the speaker settings set at?
* Did you calibrate with an SPL meter?

My guess would be that maybe your speakers are set to large with the sub = yes. This could only send a signal to the sub if there is a defined LFE track on the source.

My speakers are set on large, as for cable Iam using a cable made special for subs. So I think that is line out. And no I havent done a test on it.

Yup, that's the line level connection. It's generally considered the simplest and most surefire connection method for the sub. OK, maybe we're getting someplace.

Try setting all your speakers to small with the sub = yes.

Then play some cd's or video games (NOT A DVD MOVIE) and see if that helps. Play with the sub's volume and input level alittle to see if you can get some sound coming out from something without an LFE track.

Okay thanks around what should my cross over frequency be? And should my phase be at 0 or 180?

Anytime. With all your speakers set to small and the sub = yes, the receiver will probably automatically insert the crossover in the path. If you can choose one, 80hz or 100hz are pretty standard. The phase....Short answer: Try both and leave it where you think it sounds better.
