Do not count on help

I use this product on a 16/9 screen to convert VHS PC. The working window does not fit, at least not alone, the screen size. I asked twice for help I did not get it. It really exists Microwave Applications?
To save my tapes, I have to work with the screen in portrait mode (resolution change (4/3) did not change anything).
If the use is not quite as simple as we said, but it works with a little practice.
