When you choose to play disc menu of a Full Blu-ray WITHOUT menu, you CANNOT change the current audio track. See pictures below. First you start playback with the second option (play disc menu). In this scenario, when you open popup menu, CANNOT change the current audio track because this Blu-ray has NO disc menu: However, in this different scenario, you CAN change the current audio track because this different Blu-ray has indeed a disc menu built-in. I have not tested this with DVDs, Zidoo team must investigate this scenario too. Tested with firmware 1.4.6.
Please re-read my first post. I meant: You can change the current audio track when user selects to play the main movie, regardless this blu-ray ISO/folder has or not a built-in menu (OK) You can change the current audio track when user selects to play an EXISTENT disc menu in this blu-ray ISO/folder (second option) (OK) You CANNOT change the current audio track when user selects to play a NONEXISTENT disc menu in this blu-ray ISO/folder (second option) (WRONG). This is clearly a bug. It has nothing to do with commercial ads. If you see carefully my pictures, you'll realize that my samples are not commercial ads, they belong to the main movie and you cannot change the current audio track because this option is not available on popup menu. I hope you understand this. Thanks.
