I have already converted all my CDs to lossless files and with 300-ish ... they fit on a 500GB hard drive with room to spare so the whole process was so much easier than I imagne it will be with my Blu.
I will "start" with my small remaining DVDs... I never keep DVDs when I get a blu ray... (I don't care about special features--- just personally) The DVDs will be easier for one thing because I have so few left.
I'm still unsure about the Blus ... seems like I would need a very nice NAS setup ... if I wanted to rip all of them ... I suppose the end result would rival Kaliedescape ... sort of ... could be fun .. time will tell.
