I've lost it's box and there are no other inscriptions on the card,
except for a big "PixelView" sticker overlapping the sticker with
the model of the tuner itself. I believe that the exact model
is PlayTV 2, but I'm not absolutely sure on this.
The chip is inscribed Conexant Fusion 878A and the sticker of the tuner
is TNF-9935-B/DFF.
The only 2 visible chips on the card are labeled 0451CIRUS
(I couldn't lookup this) and 74HC405D (multiplexor of some kind).

The xawtv and fxtv both reported error initializing bktr.
Being a complete layman,
I'm almost sure the next section will make someone laugh, but anyway
I hope it may contain some useful information.
I've determined that the function
locate_eeprom_address in bktr_card.c
fails to detect the eeprom address on the I2C bus.
After hardcoding the address A0 for the I2C EEPROM address, which I
think is consistent with an example in the documentation of the chip
(See http://www.conexant.com/servlets/DownloadServlet/100600B.pdf?FileId=443,
3.5. Serial I2C EEPROM Interface
I ve got the following output at the initialization time:
bktr0: <BrookTree 878A> mem 0xf4000000-0xf4000fff irq 18 at device 0.0 on
pci2
bktr0: [GIANT-LOCKED]
bktr0: Warning - card vendor 0x0000 (model 0x6403) unknown.
bktr0: MT2032: Companycode=3c3c Part=3c Revision=3c
bktr0: MT2032 not found or unknown type
bktr0: Pinnacle/Miro TV, Temic PAL I tuner.
So, If anyone give me a hint what's next I'll be thankful :-))
Btw, is it possible that there is no eeprom at all ?
