I did a bad thing. I got a Sony DCR TRV 350 off E-bay and it has issues. It recoreds great onto tape and from tape thru firewire to computer. BUT when i try to view it to tv or imput TV to it the picture is off frequency. Thru the I/O port and thru the S video port as well. Like in the old days you had a fine tuning knob you could fine tune the channels . It seems like if I could fine tune the channel input it would be fine. Are they any known button combinations that could be pushed to get fine tunning?
