The R3K DTS track has a bit more detail and presence than the DD5.1 as you'd expect. Both tracks blow the stereo on the R4 away, so much clearer. Really improves the viewing experience.
Tough to call the video. The R3K is a lot cleaner, far fewer dirt specks and scratches and this is very welcome. But as a result of more cleaning it loses a little grain and detail and it doesn't look as good as the R4 in places.
The R3K has a better subtitle font but the R4 subtitles themselves are better. The R3K has bits of Engrish and errors throughout, nothing really bad but you notice and it does distract a somewhat. Additionally, in a few places there are timing issues such as subtitles appearing 2-3 secs before dialogue is spoken.
Personally I'm going to buy it. The audio more than makes up for any shortcomings in my opinion.
