When I ordered my component>S-Video converter directly from Lenkeng, it came from China, and took a couple of weeks. If I'd wanted to return it, who knows if I could have? I ordered it from a link posted in this forum somewhere.
Besides my Lenkeng and Monoprice converters, I have an eBay Audio Authority
converter, with component pass-through. As I've said earlier, it does have a better picture. I just replaced the bulb in my DLP TV, so it looks like new again, and the better PQ is even more evident. But, it has some problems.
I have a Comcast Moto DVR. If I output a SD channel over 720p (my TV's native resolution,) the resultant picture is pictire-boxed, and can't be zoomed to properly fill the screen. the AA converter does pass 480p, and that works fine for SD channels showing a 4x3 film. But, with a SD channel showing a letterboxed film, the AA converter has a hard time locking on the image, and centering it top-to-bottom, There are various ways to trick it into locking on correctly. They can be a PITA, but they are doable.
However, when you have a LB 4x3 image, and small, rolling credits on a black background, it loses its lock, rolls, goes black, just freaks out in general, and I have found no work-around. I will be using the LK converter on such films in the future, or perhaps I'll use it just for the credits, and tack those on.
