Hi marxian,
I have several problems since 1.x Version:

1. Vimeo is not working for me at all.
Searching just shows @Loading forever.
I created an account for vimeo thinking I might need one to make it work, but cannot add it to cutetube: Unable to obtain vimeo request token.

2. For youtube the small (un)subscribe button in the video list view does nothing at all. Not even an error msg. The big (un)subscribe button in channel info view works fine tho.

3. Scrolling in a video list often races out of control, sometimes making the app crash.

4. Twice now I had the problem that no video at all, not even known good ones in the archive, would play on the cutetube player. It just shows the black screen with Loading... in the center for a while and then crashes the app. I have to reboot the N900 to fix it. Never happened before 1.0.

I still really love the app
