Query: Product doesn't live up to its claims

The product supposedly handles an HD source. Sort of. Yes, it does allow an HD TV to display an HD source, but every few minutes, it drops the signal and your TV goes blank. It does recover after a couple of seconds, but obviously this shouldn't happen.The product is supposed to up-convert composite input to component output. Nope. Composite video up-conversion gives you a black-and-white picture or at best a "washed out" color picture, which may "roll" as well (readers old enough to remeber TVs with a "vertical hold" will be familiar with how the picture would sometimes "roll").
