SLT-A77 NTSC and PAL Issues

[dhxdltx]

My camera is SLT-A77, the machine is the Chinese PAL version, and the video is only 25p/50p.
There is no option in the menu to switch between NTSC and PAL formats.
When I tried using pmca-gui
When "Enable PAL/NTSC selector&warning" is selected, the video format in the menu is 25p/50p/50i, and there is no switching option in the menu. The captured video is in the corresponding format.
When "Enable PAL/NTSC selector&warning" is unchecked, the video format in the menu is 24p/60p/60i, and there is still no switching option in the menu. At this point, if you shoot a 60p video, the file will still be 50p. When selecting 24p or 60i, press the capture button and the camera will freeze until the battery is removed.
If someone could help I'd appreciate it.
