I searched many mailing lists for this. But yuo're right. The bktr 
development doesn't continue since 2000, there is only some 2.19 devel 
version available also from 2000. It would be greate to start a new 
project maybe based on the original bktr, inspired by bttv. The problem 
of many newer TV cards is, that they have separate audio device (see the 
last line):

bktr0: BrookTree 878 mem 0xee003000-0xee003fff irq 5 at device 11.0 on 
pci0
iicbb0: I2C bit-banging driver on bti2c0
iicbus0: Philips I2C bus on iicbb0 master-only
iicbus1: Philips I2C bus on iicbb0 master-only
smbus0: System Management Bus on bti2c0
smb0: SMBus general purpose I/O on smbus0
bktr0: Card has no configuration EEPROM. Cannot determine card make.
bktr0: Pinnacle/Miro TV, Temic NTSC tuner.
pci0: unknown card (vendor=0x109e, dev=0x0878) at 11.1 irq 5

That makes current bktr driver quite unusable, since the driver 
structure don't have any space for this info. Bttv has. I saw some 
patch, that changed this struct, and added a field, that signalises a 
separate audio device. Unfortunatly I was not able to compile the 
patched driver.

So I think the bktr driver would need a deeper rewrite for this support. 
But it needs to be done.

BT878(Prolink PV-BT878P+4E)

[Michael]

Has anyone had any success with this TV-Tuner BT878(Prolink PV-BT878P+4E)?
Any thoughts on if any generic drivers could work?

Thanks.

The bttv driver, bktr, hasn't had any major updates for over 2 years
now, and so doesn't support the newer cards or tuners.   Even Linux
struggles to use my Pinnacle PCTV Pro card (bt878, tda9887)  with the newest 
drivers.   I've seen quite a few posts about TV cards recently, maybe we need a 
project to either port bttv/v4l2 from Linux, or start a new project to properly 
support tv cards in FreeBSD?
