On further investigation it looks like the tuner is not tuning to any frequency because of the following messages in dmesg dump:
ivtv0: i2c hardware 0x00000008 not found for command 0xc008561c! ivtv0: i2c hardware 0x00000008 not found for command 0x4008646d! ivtv0: i2c hardware 0x00000008 not found for command 0xc008561c! ivtv0: i2c hardware 0x00000008 not found for command 0xc008561c! ivtv0: i2c hardware 0x00000008 not found for command 0xc008561c! But I don't know how to fix this.
