not quite HD DVD

I have a 720p50 project which I'd like to keep in that format and I'm willing to make a little inaccessible. Making a Blu-ray disc would be proper, but since the project is just 40 minutes long might a pumped-up DVD be just as accessible? I used Compressor to make an MPEG-2 having 12 Mb/s (average), 18 Mb/s (max) bitrate. I used DVD Studio Pro to burn the disk. At least one player can play the disc beautifully: Apple DVD Player. What fraction of contemporary DVD players can handle those bitrates and play this (not quite HD) DVD?
