Yeah, I have the HK BDīs of Police Story, and even though they are upscales, in comparision to the latest HK DVDīs, the BD:s donīt suffer from DNR and bad compression. Also the colors are better on the BDīs, and the upscale is sharper and better looking than what even my Oppo player can do. So itīs still an slight upgrade, if you (like me) hate DNR and compression artifacting.
But if you are satisfied with the latest DVDīs and arenīt bothered with DNR and artifacts, then itīs not worth it.
Watching my filthy collection on Super 8mm, VHS, Laserdisc, DVD and Blu-Ray.
