The plug-ins for the 5th Gen Archos players are apparently no longer available, even from "aftermarket" sources (where I got mine).
I can't believe that they've left us in the lurch like this. My 30Gb 605 is in perfect working order (the only problem I ever had was with my first battery dock which malfunctioned within a year and was swapped for a new one by Archos). Although my phone plays videos really well it's tiny and doesn't hold much so I much prefer to take my Archos away with me loaded up with viewing material. Up to this year's holiday, the majority of files have been in the avi format. This year, I've found that most files seem to be mp4s.
Do you know of any workaround that would enable me to use the Archos that doesn't involve:
a) Converting the files
b) Watching the videos on my (tiny) phone.
