First, many, many thanks to Mike Kobb for taking the time to reply.. it's good to know that it's at least "still on the list," even if it is proving very difficult to do - that means there's still hope.
A number of folks have suggested perhaps releasing a partial solution - let me add my voice to their pleas. I'm sure Roku would love to provide a complete, 100%, working solution. You seem like the kind of guys that take great pride in their software, and who don't rush to release half-baked code - as a former software engineer and current IT manager, I can really appreciate that.
But, given a solution that works for all formats may not be feasible, why not release something that works for the formats that are possible? I think many, many of us would be happy with some sort of solution that allows us to ff/skip through simple MP3's, and would be quite understanding if the release notes / user manual said "doesn't work for DRM'ed files.." Heck, you could even write it so attempting to FF on a non-supported file flashes a message on the unit say "not supported on this format" - or some such.
Anyway, thanks again for your hard work. I do appreciate your continued attempts to improve what is allready a fine product.
