My player is in a spot where it collects a fair bit of dust.  So far it hasn't been too big of a problem, but I know I will need to clean it out soon.  Has anyone else had to deal with this yet?  The instruction manual says do not use a cleaning disc that was designed for CD and DVD.  Maxell now has a cleaning disc out for Blu-ray and HD-DVD.  Has anyone tried it, or would it be better just to open the thing up and use a can of compressed air?
