It's likely a combination of exposure and mount problems.
What is your scope and mount, and how are you aiming the mount?
I have a camera that is similar to yours and I have no trouble locating the planets. I use a daylight video exposure and frame rate to locate, then I fiddle with exposure until I can see well enough to nail focus and position. Then I fine-tune exposure, which is generally a matter of finding the right frame rate for the seeing and then making very small incremental changes to focus, coupled with any change in gain or other exposure factor needed to get the best image possible.
If you don't use a focusing mask, you can focus on the satellites (focus until they are as small as possible).
If your seeing is average or worse, nailing exposure and focus are very difficult.
But if you are having trouble with aiming, everything will be very much more tedious. With an equatorial mount, a good polar alignment is a very big help. I don't usually drift-align for planetary imaging, but I do get it as close as possible with a polar scope and then make very small incremental changes while watching a low-magnification image on screen. When I use the software supplied with the camera (IC capture with the DMK and the standard Philips software with the ToUCam or NC), I put the planet in one corner of the field of view to make it easier to tell which way to move the mount. When I use K3CCD, I use the centering reticle cursors.
Start with low mag to make acquisition easier, then move up in mag in increments, checking aiming as needed. Finish with aligning using the same image scale you will use for capture.
I often find that once I insert a barlow (I use Powermates), the focuser sags a bit and I have to realign.
