Another thing you'll be really thrilled with is that an Archos recorded Copy Protected file will not play on any other device but that specific one. It won't even play on a replacement of the same model!
Here's another fun fact you may or may not know...you can't play your Copy Protected videos through any output other than the built in screen!
Also, transiting Venus needs to be in Trine aspect to your natal Neptune but only while transiting your 5th house!
Just kidding about that last one.
Poor Sony has conflicts of interest when it comes to copy protection and has only recently appeared to rise above a level of mental retardation (after many years of banging their heads against a wall) in this area--think MiniDisc, SonicStage. Their tactics my very well be to blame for your buggy situation involving their equipment.
Do other Archos owners with non-Sony equipment have Copy Protection invoked on their own content?
