I have successfully created a (pretty much) fully functional non-standard 1080p24 3XDVD using free software. It plays on my A30 with occasional stuttering, I think the stuttering can be eliminated by lowering the max bit rate. Here's how I did it:

1. Encoded HV20-sourced IVTC'd 24p 1440x1080 video in HCEnc using the following settings:
*INFILE k:\hdv\proc3\batch_file_0.avs
*OUTFILE K:\HDV\proc3\ACAMeeting_1080p.m2v
*BITRATE 20000
*MAXBITRATE 23000
*FRAMES 0 13992
*PROFILE best
*AUTOGOP 12
*DC_PREC 10
*PROGRESSIVE
*PULLDOWN
*MATRIX mpeg
*COLOUR 1

2. Encoded AC3 file with BeLight at 384 kbps.

3. Muxed the video and audio into a MPEG2 program stream with Avidemux 2.4 preview 2.

4. Authored a DVD with DVDAuthorGUI using the muxed file.

5. Burned DVD folders to DVD with ImgBurn.

6. Play.

The advantage of this method is that it will be playable in at least some software DVD players on computers with standard DVD drives. Another advantage: I haven't tested it yet, but I suspect you could have both a SD and a HD title on the same disc, allowing playback in SD DVD players.

I haven't tested it with standalones other than the A30, I would appreciate if others could test this method with other players.

Obviously, this is a sub-optimal method for creating HD DVDs. However, I believe it to be the only free method demonstrated so far. What we really need (or at least I really want) are free tools for creating true 3XDVDs/HD DVDs, complete with next-gen codecs. It may ultimately be a foolish endeavor, but then again, why shouldn't we adopt this all-but-completely-abandoned format as our own? I hold out the hope that perhaps the HD DVD standard will be opened to the masses, giving the amateurs and independents a format to call their own.

NOTE: This is a direct copy of my post from AVSForum. I'm very excited to share this new development, and see no reason to retype it all.

ADDITION: This technique also works with 480p60 footage. I had limited success with 1080i60 footage, which had stuttery playback, but I think this problem could be eliminated by lowering the bitrate. I've yet to test 720p footage, but I suspect 720p at 30 and 60 hz would work, while 720p24 would be difficult to accomplish in an efficient manner.

YET SOME MORE: There is further discussion on this topic at AVSForum http://www.avsforum.com/avs-vb/showthread.php?p=13160616#post13160616 and Eugenia Loli-Queru's blog http://eugenia.gnomefiles.org/2008/02/19/creating-an-hd-disc-in-plain-dvds-for-free/
