I have an 8.10 machine just sitting here getting regular updates, I am offering to be a guinea pig here, if there is anything that you need tested before you submit let me know if I can help out.
I have several sound cards 2 or 6 channel analog, spdif or hdmi as well as video cards, monitors, remotes, etc... That I would be happy to test out if asked, I have a duplicate gparted drive so screwing things up is a non issue, I just make a clean copy from the backup drive and start over. I have both Fiire and Gyration remotes as well as several M$ and SMK (Hauppauge) MCE remotes.
happy to help if I can.
My recommendation is to just get testing rather than wait for someone to give you direction...look in the Trac database to see whats already been reported...or add some additional info you've seen on your install.
Trac is here http://svn.linuxmce.org
All the best
