Problems with zoom when Full Screen Video on TV (GF5600)

I've got a GF FX 5600 and in general everything is OK. The only problem is with TV Out. It also works properly, but when I want to see a film on TV it is always zooming it so I cannot see left and right edges of the film or subtitles if it is of 4:3 ratio. This is I presume caused by Full Screen Video bookmark in Forceware drivers. If I turn it off I don't see anything on TV (i.e. I can see everything, but the video).
What's really strange is that earlier I could activate clone monitor+tv and everything was fine. Then, when first problems occured, I just cloned tv+monitor and it was ok. Now nothing helps. The video on tv is always zoomed.
I cannot do anything to turn out zoom completely. Is there anything that can help? Any possibility of changing something in registry? TVTool didn't help unfortunately...

 

is yout tv an old crt type, like 21", or is it a modern flat screen tv with higher hz like 100hz, becouse before my tv broke, i was trying to use the computer on the tv, and everyhitng worked exept the video, so i presume if you have an old tv, thats to blame :\

 

Which program are you using to watch the films?

 

I mainly use 2 progs: WMP 10 and All Player.
As far as my TV is concerned I have 29" 100Hz LG TV with PIP so it is rather new hardware

I tried to install drivers earlier than forceware, I used detonators 43.03 and Omega Drivers based on detonators 45.23 and everything is working properly.
When I got back to forceware, the problem returned. After installing RivaTuner 2 I found an option to turn off zoom in overlay, unfortunately it didn't help.

 

, new hardware, yes it is , ok well it is not your tv then, i am tottaly confused myself now.

 

You might also try Intervideo WinDVD 5 or 6 as they let you change the aspect ratio between 4:3 and 16:9 and also zoom!
