I have a couple of questions about the current freebsd bt848 driver

- why is BROOKTREE_PAGES so large?  it seems like it should be, worst
case, pal rgb (768*576*4)/4096 = 432.  NTSC looks like
(640*480*4)/4096=300

the "217*4" does not make sense to me...  (I get the 217 - for 16 bit)

- is bktr_read missing a call to "start_capture"?  the "examples/single.c"
program I have from my meteor days hangs in the read of a single frame...
