The new version is only updating 1 line of code in the file /opt/cutetube/youtubeservice.py to fix the video playing problem. So you can either edit that file yourself or install the update which will give you the same result. I personally prefer editing the file myself in the xterminal with leafpad than running the update since I have made some cosmetic change to the app and don't want them to be replaced with the new version. Marxian..! Correct me if I am wrong..
