Anyone know if jerky NTSC playback is the norm for budget multi-region machines? I have a Wharfedale DVD750s and find it stutters noticeably playing Region1 discs. NTSC VHS tapes are fine so it is not a display problem. The problem occurs with both S-VHS and RGB connections. I plan to upgrade to a PAL and NTSC progressive scan machine soon. Anyone have experience of multi-format DVD-A/SACD PAL/NTSC progressive scan players?
