First of all, thanks for Wieslaw giving so many information to help me. Actually, I know the brand of the tuner is Philips one. But, I can't find any further information in all things along with the TV card. I just know the card is PAL I and PAL D/K as I found it written on the card like the photo in this link: http://www.geocities.com/ellen_yip/200.jpg Moreover, when I use the command "dmesg", the following messages were found: i2c-core.o: adapter bt848 #0 registered as adapter 0. bttv0: using tuner=1 bttv0: i2c: checking for MSP34xx @ 0x80... not found bttv0: i2c: checking for TDA9875 @ 0xb0... not found bttv0: i2c: checking for TDA7432 @ 0x8a... not found i2c-core.o: driver i2c TV tuner driver registered. tuner: chip found @ 0xc2 tuner(bttv): type forced to 1 (Philips PAL_I (FI1246 and compatibles)) [insmod] tuner: type already set (1) i2c-core.o: client [Philips PAL_I (FI1246 and compa] registered to adapter [bt848 #0](pos. 0). bttv0: PLL: 28636363 => 35468950 .. ok bttv0: registered device video0 bttv0: registered device vbi0 bttv0: registered device radio0 tuner: TV freq (268435455.93) out of range (44-958) Do I still set something wrong with the tuner? May anyone please kindly help me? Thanks very much. __________________________________ Do you Yahoo!? The New Yahoo! Shopping - with improved product search http://shopping.yahoo.com
