Jsattv,
I managed to duplicate a freeze-up on my AZbox Premium Plus with firmware 0.9.5309 using YouTube.
I watched one video clip, then I tried to change the category (MOVE CATEGORY) and it went off into never-never-land. When I tried to exit to TV mode, it went there, but wouldn't bring up the channel that I was last on or even my channel list. I tried to go to MOVIES and it wouldn't trigger the HDD to wake up. I had to reboot to get the box to respond properly.
After getting the TV satellite list and channels to pop back in and function properly, I went back to YouTube and tried searching for a specific song. It pulled up a list of songs, but when I tried to view and load one, it either gave me a message about YouTube filter blocking it or it sat there LOADING forever. When I tried to exit, it was locked up again. It would go to a new menu, like TV but it wouldn't load the channel list and it was just sitting there waiting. Had to reboot again.
