|Rose, The (1979)||R4|
The Region 1 release of this film is quite similar to the Region 4. It has the Dolby Digital 4.1 soundtrack as its main audio, it includes the commentary, but it also has a French soundtrack. It offers just English and Spanish subtitles.
The Region 1 disc is reported to be single layer, which would mean that it was probably more compressed than the R4. That would not help video that's already impaired by grain.
The Region 2 disc is, by all reports, identical to this one (given that this disc is coded for regions 2 and 4, that's not surprising).
At a guess, I'd suspect that the Region 4 would be better, because it's spread over two layers, and therefore doesn't need to be as compressed.
