Wish I could say the same about the DMR-ES20. I tried two of them, both of which were new "in the box" models from Circuit City. Both exhibited faint but visible interference bars, mainly noticeable during dimly lit scenes.
The problem was in the video input section of the ES20, both S-Video and Composite In. A DirecTV receiver was the main signal source, but I also tried recording images fed to it from an older Panasonic DVD player, using test signals from the Avia Home Theater disc. Interference was still visible, so at this point I reluctantly gave up on the model. During searches on the ES20, I noticed a few comments from other users with similar complaints.
Personally, I would try the ES15 first, based upon my own experience with the ES20. I live in the US, and the ES20 also had a stereo tuner here by the way. I think Lite-On is pretty much alone in their decision to stick with monaural tuners.
