[QUOTE="Zarathrustra, post: 385900, member: 86197"] Quite a lot of stuff is Variable Frame Rate, if it's been encoded properly (which is usually isn't). Most NTSC Sci-Fi DVD's have 23.976 film rate for the normal scenes, and 29.97fps progressive for the special effects/CGI stuff (Stargate, Babylon 5, etc), so should be encoded with VFR. The new episodes of Lost are (should) be the same, as it's the only way to combat the screwed up broadcast ABC are sending out for that show (timestretching, to fit in more ads, screwing up the telecine pattern), although it's still not ideal. Best solution I've found for this, is to set ntsc_Hz (60hz) as the default refresh rate, and have it revert back to that every time playback stops. i.e. <entry name="default_hz">ntsc_hz</entry> <entry name="use_default_hz">yes</entry> That way, because the refresh rate changer doesn't know what to do with the variable frame rate, it does nothing, and leaves the refresh rate at 60hz - which is generally the best (realistic) fit you'll get for most vfr encodes. I usually don't bother with setting a default_hz, I just leave it set at whatever the last thing played was. But, as 90% of my stuff is 23.976fps, the refresh rate is generally always at 24hz. Playing one of the latest VRF "Lost" encodes at 24hz is shocking, all it does is stutter (Refresh rate Changer can't tell what it is, so does nothing) Setting default_hz to 60 has solved the problem for me, and the new Lost encodes look fine.
