hi guys, i'm looking at getting an n810 but before i do i want to be sure i can transfer and watch my favourite feature length dvd movies onto it so i have a few questions. 1) do i need any additonal software? 2) do the movies need to be compressed first? 3) how much space does an uncompressed and compressed movie take up? 4) how many movies would i be able to save to an 8gb card (apparently this is the largest size the n810 will accept)? 5) have i missed anything? all help greatly appreciated. cheers!
