MININ DV TO ARCHOS
Initially, it would work better if you can provide the specific model numbers of the Sony Mini DV Cam and the Archos. Assuming all things even, most DV cameras have an analog A/V video OUT, in turn some Archos with recording capability have an analog A/V video IN. If this were the case, then it would be a matter of getting the right connectors/plugs + cable and/or adapter/interface.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information. Good luck and kind regards. Thank you for using FixYa.
