The TV I bought recently has the vga hookup in addition to all the other inputs.
The VGA input would be best, but most don't go over 1024x768, unless you paid 3000+ for your TV. it's still good for DVD though. I paid 1000 for my 32" LCD about 2 years ago. I have an LCD projector connected to it too, so when we watch a movie we get the big 9' screen....but anyway.
RAID5 Storage = number of drives - 1. If one drive goes bad then you can just put another drive in and rebuild what was on that drive. The RAID card does it by comparing (XOR) the data on the two drives byte by byte.
RAID 1+0 - you need at least 4 drives. Storage = 1/2 number of drives. You can lose up to two drives. It works by combining (raid 0) two mirrored arrays (RAID 1). Hence the name Raid 1+0.
RAID 1+0 or 0+1 (same thing basically) is "safer" than RAID5 because you can lose 2 drives and don't lose data, but I don't think you really need it, unless you're like me. I wanted to do RAID6 when is like RAID 5, except its redundant to 2 drives. You need at least 4 drives for RAID6.
I think the more drives you have the more likely that two will go bad at once. I'm going to add another RAID card and do two RAID6 arrays. Those 1TB drives are getting cheaper. I only have about 200GB of space left now.
I rip all my DVDs to the hard drive in raw VOB format, so they take a lot of space. The only ones I convert are the ones that have bad quality video (old movies). I have some old B/W movies. I put EVERYTHING on my HTPC, even important documents.
I use a free program call GB-PVR. It works like Windows Media Center. It's not as pretty though. If you convert all your DVDs then MediaPortal is better. It looks more like WMC, but it won't play raw VOB files for some reason. I don't know why they didn't program that into it. For TV capture, I have an ATI All-in-Wonder 2006 version PCIx card.
