I have not yet tested your code, but PAL/M is just like NTSC when dealing
with B/W format. In other words: 525x60 and not 625x50...
It's the M suffix that defines B/W mode.
Hey guys, remember: PAL is a TLA for Phase Alternated Line. It does not
specify a resolution, but an encoding of the color signal.
// case BT848_IFORM_F_NTSCM:
// case BT848_IFORM_F_NTSCJ:
// - case BT848_IFORM_F_PALM:
That's why this line was here...
// case BT848_IFORM_F_PALBDGHI:
// case BT848_IFORM_F_PALN:
// case BT848_IFORM_F_SECAM:
// case BT848_IFORM_F_RSVD:
// + case BT848_IFORM_F_PALM:
...and not here. And this part of code works. I use it everyday. :)
