Hi,
I have a G5 and a MBP all currently hooked up (wired and wirelessly) via a D-Link D634 cable modem router. I also have a Squeezebox 3 which is serviced wirelessly by the D-Link as well - all my music is stored as Apple Lossless on the G5 (and backed up to 2 separate external USB drives - I learnt the hard way and don't take any more chances than I have to nowadays

).
I have just bought a TVIX 4100 media player, which I love. The purchase of the TVIX has now led me to want to rip all of my DVD collection (in the many hundreds) to hard disk (I'd strip out everything except the main film, english 5.1 audio and english subtitles - I'm even going to strip out the end credits where possible so save another 100MB or so per film) and use the TVIX as a video jukebox.
Now, this is obviously going to involve a massive amount of storage - somewhere around 4-5TB and I'm not sure of the best way to go or what products I should be looking at.
I'm guessing that some sort of NAS would be the best way to go (so long as I can get the TVIX to see the NAS - right now I can't get the TVIX to see anything on the network, even though it's hard-wired to my Squeezebox and using the Squeezebox 3 wireless bridge feature) and maybe even a RAID NAS (don't know much about RAID, but I was thinking of maybe RAID 5 for redundancy).
I am hoping that some of you have some advice or even experience that you could pass on to me. I would be very grateful if you could.
I'm in the UK, so I may be kind of limited to the equipment make/models that I have available to me.
As ever, many thanks,
Matthew
