Hi all!...
I tried the new bttv driver (version 0.7.102) to try to fix the
unclear image bug but with no result. I still got a very unclear
picture. Works good with Windows... : (
Here is my dmesg

Found the problem: bad isolation between the radio antenna input and the
tv antenna input that caused interference of the cable tv signal by the
signal captured by the radio antena (strong tv stations in my area).
