Hi, I have an Archos MMJB20 that is 2.5 years old. This has been one of the best things I've ever bought - even the Mrs agees with me on that one... no mean feat, I can tell you! Anyway, I'm thinking of upgrading it to the AV420 or AV480. One question is... will I simply be able to transfer my current movies onto it, or will they all need re-converting? I have converted all my DVD's for my MMJB20 and have read that the new 400 series won't let you view ripped DVD's externally - only on it's own screen. Can anyone clarify please? Thanks.
