Finally switched from my old Roku 2 to my new Roku Express+, and I've encountered some strange playback issues when trying to watch a video. The quality of the AV connection itself seems fine, since the user interface displays correctly as far as I can tell (the app interfaces are very different from the ones on my Roku 2). At worst, the fonts and some of the cover photos are slightly out of focus, but it's not too noticeable. However, when I try to stream a video, the audio is muddy and at a much lower volume than what my TV is actually set to, the subtitles take up nearly half the screen regardless of my chosen settings, the video is often grainy, and occasionally I even encounter warbly downward-moving horizontal interference that reminds me more of an old CRT television with a bad picture than anything I ought to be encountering on any present day TV. Again, this only happens when I'm actually streaming something. Normally the picture is fine.
