Ok, I have figured out what triggers the issue of getting stuck in a particular category. As I posted before, I was stuck in the "cinema" category and could not get out of it. After rebooting I was able to get back to "all" category. This evening I again got stuck, this time in the "entertainment" category. I have figured out what is triggering this bug; direct channel input. If I fire up the Buzz TV and all channels are selected I can scroll through the list of channels on the left side and select any channel just fine. However, if I'm on channel 300 HBO and want to go to AMC channel 131 and don't want to scroll through the entire list of channels to get to AMC, I will type in "131" and go directly to AMC. This causes the Buzz TV to select the category AMC is in which happens to be "entertainment" and now I am forever stuck in this category unless I reboot the box. Yes, I can select "all" again and get the list of all the channels and even select them but when I check the categories list again I'm back to the category I'm stuck in. Also, when I pull up the guide I only get the channels in the category I'm stuck in. I cannot find a work around for that except rebooting.
