Hi, There will be a major cuteTube update soon, hopefully within a couple of weeks. However, I think the issue that people are having with downloaded videos is that many 480p YouTube videos will not play on the N9 following the PR1.2 firmware update. 720p videos could never by played as the N9 has only very limited support for 720p video playback. Unfortunately, there is nothing that I can do to fix this. I have not had any other kind of reports about downloads being corrupted, but I will be making changes to the download process anyway as part of the update. Best regards, Stuart Howarth
