It could be a number of things affecting your image, I'm afraid I'm not experienced enough to tell you exactly what it is from your images. To maximise your chances of capturing a good shot of a planet you'll want to do a number of things:

Record when the seeing is good, usually later when the air is cooler
Avoid shooting over buildings or through windows
Capture it when it is fairly high in the sky
Make sure as little glass is in the way, so no diagonal
Make sure the telescope has cooled down
Focus precisely, a batinov mask can help with this
Record with a high frame rate, using a smaller ROI and high gain will help with this
Make sure you don't record for too long, planets rotate this can add motion blur to the image, depending on the target 1-2 mins is probably a good max.
Watch some videos and/or read tutorials on autostakkert and registax, the amount and levels of sharpening can mean the difference between ok and fantastic images.

And finally practise, with experience you will be able to watch the camera feed and know wether Jupiter is jumping around too much to record or if you have brought all you can out of your image. Of course you might not be able to get everything but do what you can. The challenges are what makes the reward all the sweeter.
