I am a happy new osx user for two weeks now. Previously I used Youtube grabber for Windows. Always did the job nicely.
Searching for a osx replacement was though. Tried a couple but other then iTubex I could not find what I was looking for. With iTubex I had some difficulties downloading at garage tv and some obscure sites. But in general iTtubex is good enough to register.
Today I stumbled on iTubegrabber. What a great program. It reminds me of Youtube grabber but with a better osx interface.
Glad I didn't register iTubex because for now I can use iTubegrabber for free.

After downloading a whole set of videos I can already say this is the program I was looking for. Hope this stays free if not I will pay for it when it is cheap.

Kudos to the dev for making the beta useable for everybody.
