Well, I have been using this box for a few months now over component cables and it looks great. However, I only have 2 component inputs on my Samsung HL-T5087S, so I decided to try the cable on HDMI. Once I plugged it in, it seemed to work fine, but it was changing the resolution when I switched the channel. So, I went to the settings and unchecked all but the 1080i option and the box set itself to only 1080i and it stopped switching. All was working fine, but then I went to the guide, browsed for a bit and when I went to exit the guide, the 1/4 screen video that was up in the guide stays there and leaves the rest of the screen black. When this happens the box is saying 480 on the front instead of the normal 1080i.
Has anyone had this problem? I would like to keep the box connected to HDMI so I can use the component for other devices. Also, image quality seems to be worse than with the component cables, but if anything shouldn't it be better since it doesn't have to convert to analog and back to digital?
