Re-reading that, it appears you are correct. This leaves me wondering why so few players support 24 fps playback for DVD as it seems like it would be fairly simple. Taking a guess, it's because until the common and cheap availability of progressive flat panels, it wasn't really a selling point. And once it was, blu-ray and HD DVD had already grabbed that market. | | | | First registered: February 15, 2002 |

Well, Oppo tried it on their BDP-83 and abandoned it for its successor, the BDP-93, the reason being that all too many DVDs are poorly authored, producing less than favourable results on 24 fps (tearing issues and so on). I always find it a bit amazing that people can't take a little more time or use a bit more skill in what will be an enormous pressing affecting the enjoyment of so many viewers. |

I always find it a bit amazing that people can't take a little more time or use a bit more skill in what will be an enormous pressing affecting the enjoyment of so many viewers. As I recall, many Oppo 83 owners who were seeking to upgrade to the 93 were putting the pressure on Oppo to carry the 24 fps feature over to the 93/95, but Oppo wouldn't budge, stating that the feature didn't produce results to match their quality standards. To be fair, the results with NTSC discs on my 83 are indeed mixed (on PAL it doesn't work anyway), but on a well-authored disc to me the result is clearly visible and positive. Might be a chicken-or-egg issue: since so few players support the feature, disc authors don't care to do it properly. | | | | Last edited: by dee1959jay |

| | Posted: | | | | From reading on on it a bit more, it looks like we were both a bit right. The telecining is part of the MPEG-2 standard, not the DVD-Video standard. This means if you look at the VOB files, it will report 29.97 fps, even though it's really stored as 23.976, because the conversion is part of the video metadata. This means that displaying at 24 fps would require using a non-standard MPEG 2 decoder. That may be why we don't see it more. | | | | Last edited: by Ace_of_Sevens |

| | Posted: | | | | Here's a rather lengthy and technical article that's quite an interesting read. Some parts of it are a bit outdated but the gist of it is still relevant. | | | | First registered: February 15, 2002 |

Looks like they've changed their mind: "Added "DVD 24p Conversion". This feature restores the original 24 film frames from DVD-Video and outputs it as 1080p/24Hz. To enable this feature, enter the Video Setup in the Setup Menu, set the "1080p24 Output" to be "Auto" or "On", and set the "DVD 24p Conversion" to be "On". Note: the actual DVD 24Hz conversion quality can be affected by the display’s processing and video source, especially for a non-3:2 pulldown cadence source." | | | | First registered: February 15, 2002 |
