channel locking problem.

i got T328 device from geniatech , chipset: AfaTech and module number:
af9016. also, i got ubuntu 9.10 and the device output from lsusb is:
Bus 002 Device 004: ID 15a4:9016

anyway, i was installed it correctly and i was trying to locking down channels with the kaffeine program.

i got something like 40 % signal ( i was add an link to the picture ):

some of the people in $v4l channel advice me send this email. tnx for your helping
