Thanks, Marxian. I replaced the /opt/ file you provided, and the way Cutetube works for me now is that, if you select a video from a list by pressing the description, it takes you to the info page of the video, but does not play the video.
The trouble is that if you play a video in either orientation, the related videos button is totally nonresponsive, though the comments button works as it should on that same page. Weird. I did find that, if you got to the working related videos page as descibed above, then the videos would load without crashing.
More not-so-good news: the YouTube event feed issue with duplicating entries is still happening on my device, though I still find the Daily Motion videos on the event feed to be totally free of the duplication error. I hope that this helps you troubleshoot.
