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). scanpci output: pci bus 0x0002 cardnum 0x00 function 0x00: vendor 0x109e device 0x036e Brooktree Corporation Bt878 Video Capture pci bus 0x0002 cardnum 0x00 function 0x01: vendor 0x109e device 0x0878 Brooktree Corporation Bt878 Audio Capture bktr driver initialization May 4 12:54:03 fence kernel: bktr0: [GIANT-LOCKED] May 4 12:54:03 fence kernel: bktr0: Card has no configuration EEPROM.

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: 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 ?
