Can you explain the 1st, 3rd, 4th, and 9th step in a bit more detail? I am not sure I understand due to my lack of Linux experience, what it means Make changes to /include/config/hardcoded.php to allow setting of auto and vdpau support as HW acceleration through lmce-admin and so forth. I think that just a little more detail would do. Also, are there any other steps that need to be performed?
This is not supported by the devs in any way untill it's released and I don't really recommend this is if you don't know what you're doing but... if you really can't wait.
1) The file to edit is on the core under the /var/www/lmce-admin directory, it's part of the webadmin configuration.
3) Add the avenard repo, see: http://wiki.linuxmce.org/index.php/ZOTAC_ION
4) I think brandons builds are in the nvidia-vdpau launchpad ppa repo, google search should find it with instructions for adding it.
9) Do the same as step 8 only to the file referenced in step 9.
Step 1 is performed on the core, all other steps on the MD that has vdpau capabilities.
