Research direction

Reproduce the issue by booting with sdtv_mode=3 and by running tvservice -c "PAL_M 4:3", then record the reported resolution and refresh rate. No source file or test is named in the issue, so first identify the firmware or display-mode entry point responsible for PAL-M. Done means both paths produce 720x480 at 60Hz, matching NTSC timing.

Description

bug

When I boot with sdtv_mode=3 or use tvservice -c "PAL_M 4:3" I get 720x576 at 50Hz, but it should be 720x480 at 60Hz like NTSC, that's the correct format for PAL-M.
