Installed FreeBSD 6.2 box to test bktr ffmpeg grabing under FreeBSD.
The same effect as in OpenBSD.
FFmpeg install with old grabbing interface grabs fine.
Perhaps issue specified by my card:
  bktr_mem: memory holder loaded
  bktr0: <BrookTree 878> mem 0xf3002000-0xf3002fff irq 11 at device 10.0 on pci0
  bktr0: [GIANT-LOCKED]
  bktr0: Card has no configuration EEPROM. Cannot determine card make.
  bktr0: IMS TV Turbo, Philips FR1236 NTSC FM tuner.

Maybe in old interface there where some workaround for this card...
