This is from my dmesg:

pci3: <ACPI PCI bus> on pcib3
pci3: <multimedia, audio> at device 6.0 (no driver attached)
bktr0: <BrookTree 878> mem 0xfdcff000-0xfdcfffff irq 21 at device 7.0 on 
bktr0: [ITHREAD]
bktr0: Leadtek Winfast TV 2000, Philips FR1236 NTSC FM tuner.
pci3: <multimedia> at device 7.1 (no driver attached)

sysctl -a | grep hw.bt848
hw.bt848.slow_msp_audio: -1
hw.bt848.format: -1
hw.bt848.reverse_mute: -1
hw.bt848.tuner: -1
hw.bt848.card: -1

Never changed those settings because I don't know what they mean.

Not impossible. When I start mplayer it understand PAL.
