I recently bought the Ryobi BS902 9" Band Saw as a starter saw for me. I noticed when I first started using it that as I pushed the piece of wood through, the blade itself began to curve off of the straight line I had drawn. I know that it was not me making it curve, because I had the wood sliding along the fence, so I am wondering if this has happened to other people and what I can do so that this wont happen again. Thanks.

Blade tension needs to be tighter, AND you may need to adjust the blade guides.
Here's a link showing some guides to give you an idea of what Im talking about - http://www.woodcraft.com/InhancedImage.aspx?FamilyID=904
Those guide blocks should allow the blade to slip thru them, but not allow it to twist. A wider blade will help considerably too.. makes for a stiffer band behind the teeth (if youre currently using a 1/4", try going to 1/2" if you see a lot of twist). Oh, those guide blocks should be right down close to your stock too... I like to keep mine at less than an inch from the stock surface, the closer the better.
The other things to consider are teeth per inch, and the stock material (what youre actually cutting). In a manufacturing production environment, we even get down to the tooth angle, hook and set...changing those as needed for different kinds of stock. The more teeth per inch youre using, the smoother the cut will be...if you don't need a smooth cut, then by all means use a blade with fewer teeth, and a more aggressive tooth pattern for faster ripping.

Check the blade tension, and keep the guide close to the work, if that doesn't solve the problem, with the machine switched off run your fingers on each side of the blade if the teeth on one side is smooth this will make the blade cut at an angle and the blade should be replaced, the cause of this damage to the blade is the blade pinch guides being in contact with the blade teeth and they should be moved back a little, the pinch guides should be set that the blade runs through without any play or you will get wandering.
Also check that the blade is running on the center of the drive wheel, your instructions should help you on this.
With the saw setup properly and a good blade you should get very precise cuts with no deviation.
A band saw is one of the best tools you can have in the work shop

It is a characteristic of a band saw to tend to wander. Even if you have the right blade with the right tension and the right support from the guide blocks or guide wheels. Having a wider blade helps but many times that defeats the purpose of using a band saw if you are trying to cut sharp curves.
The thicker the wood the more of a tendency for wander. Also wood with an uneven grain like most pine will tend to track along one of the harder areas of the wood.
You really can't expect precise cuts with a band saw. Good tension, sharp blades and very slow feed rates are what you need to strive for to give you the best control.

Check the blade tension, make sre it is not too loose.
Make sure the blade guide is close to the work piece.
Don't force the wood to fast, go slow you will get a cleaner cut.

Blade tensioner needs adjustment.
