Ok Cristan, try this: Frame rate no faster than 5-10 for jupiter, (can do 15 for saturn) as little compression as possible, Output is ok but you could go higher to 640 x 480. Start your brightness about half and gain about 1/3 to 1/2. Gamma on zero, saturation between about 65 -90 (depends on how intense you like your colour basically). Leave white balance on auto to start with. Exposure set to about 1/25 of a second.
Once you have these settings when you focus you should be able to see jupiter clearly enough to get a more accurate focus. Focus as close as you can get then start dropping the gain until jupiter is no longer washed out. Try refocusing again to see if you can get it clearer. Unless the seeing is great you will still get fuzzyiness with the occassional good view.
Try it without your barlow first. The barlow that is already in the focuser is a trick manufacturers use to increase the focal length of the scope. I gather that it is a fairly stumpy little refractor. Unfortunately the barlows they use for this purpose are generally not very good quality. How does jupiter focus using just an eyepiece and no additional barlow. Now when you add your own barlow how much does the image degrade. If its hard to tell try using a clear crater on the moon. If there is a large difference then you may not be able to use your own barlow as its pushing the capability of the scope too much.
Oh quick question (should have asked this first with the other questions) have you collimated you reflector yet? This can also make quite a difference.
Once you've changed all your settings and checked the quality of the scope. Try a shot without your barlow and see how it turns out. Then try it with your barlow in. If your unable to get a focus now then you more than likely have a back focus issue. If that's the case let us know here and we can walk you through the next step.
Good luck
