I have tried lots of their firmwares. The firmwares that have full market access are the worse with no catchup tv support. These have flash 10.2 Froyo built in which cannot be updated changed as I suspect that is the problem.
I have also tried several versions of the standard firmware all of which can access catchup tv but are very jerky as to be unwatchable. I have also changed the browser setting from Ipad to desktop etc. with little to no affect. Geniatech have advised me that they are working on the problem and a new firmware will be released in the next few weeks.
Interestingly they sent me a table of someone elses testing in Australia of different firmwares and settings for catchup tv so as I say they are geniune in trying to fix the problem.
