Im not apologising to you - you cant even post accurate information!
I strongly suggest you read
Page 32 of the
"Requirements Specification
for HD DVD Video Application" document, section "
5.2.1 Video Source Standards and Resolutions" where is specifically states:
Quote:
5.2.1 Video Source Standards and Resolutions
Functional Requirements:
1) Source content including film/telecine content, progressive video, or interlaced video in native format,
frame rate, and aspect ratio.
2) Support for video source resolutions up to 1920x1080 and frame rates up to 60p.
3) Support for lower resolutions (e.g. SD, SIF, CIF).
Key Performance Requirements:
1) In the case of 60 Hz region, 3:2 pull down flag is mandatory for movie (film content), which means that synchronization between video, audio, sub-picture, and advanced objects follows 60 Hz vertical synchronization signal.
2) In the case of 24p source content, when the 3:2 pull down flag is used for 60 Hz region, picture level encoding is performed on a frame-basis. In addition, such 24p elementary video streams can be converted during content creation (authoring) to corresponding 50 Hz elementary video streams.
3) The encoded frame rate of primary video and secondary video shall be 60 Hz for 60 Hz region and
50 Hz for 50 Hz region.
Feel free to continue reading the next table:

I await your apology for being flat out wrong!
