This converter works fine as far as I can tell, but maybe I got lucky. I'm using this with a 3910 Roku Express+ to convert HDMI to S-Video (Roku can do composite too, but I wanted this feature on the go). The TV I'm using it on is from 1998 and it looks very good with S-Video, but not so well with Composite. One thing to note is that Roku takes a while to load. I was a bit worried when the screen was distorted. I first tried different combinations of Roku Power and Converter and then just decided to wait. I had to press the button on the side a couple of times to get it into the right mode. You can also just make our 720x1280 and video format if you are in wrong mode. After syncing, the picture looked pretty good. The sound wasn't as good as our old Roku, but that's to be expected since I'm using an optical output. I have a fan cooling the stereo to get some air through the unit. Under these conditions, the 720P output to the converter did not heat up. I don't understand why you need to output 1080P when it should convert to 480i anyway. I would guess it's more difficult to convert from 1080P, but I could be wrong, I didn't try to set Roku to 1080P, just 720P. Bought this as insurance as our old Roku 1100n is no longer officially supported as of 2015 and could be removed. from Netflix every day. I only tested this for 2 hours to watch a movie to see how hot it gets. I'm using the old Roku until they drop support :). New to the gym :).
