After many years of using dual 300 disc carousels for my 500 plus DVD collection, I am ready to take the leap to a hard drive based solution. There are many reasons for this. While the carousels [Pioneer DVF-727's] are rock solid, they do not offer the features you get by simply plugging a DVD into the DVD drive of a HTPC. Features such as Internet based title cast and crew information, ability to watch in a window while doing other things and integration of practically everything I need [except Direct TV, sadly] onto a single input of my HT receiver make this an easy decision, even though the actual implementation is proving to be a challenge. I have no experience with this sort of thing so I am hoping to get a little guidance. My general questions are as follows. 1) I use Arcsoft's TMT5 for DVD and BD playback. It works great with physical media. Will it do the same for burned media? 2) What is the best method for burning DVD's to a hard drive and how is it done. 3) What are the best options for data security? I've looked at the Drobo products but they seem overly expensive and I've read some bad reviews. Nonetheless, some sort of data security is a must. 4) How much storage capacity do I need? I have about 500 DVD's and 50 BD's. I'll probably want to transfer only about 400 of the DVD's to hard drive since many are "features" discs etc. I will want enough storage capacity to guarantee total data integrity. In other words, I don't want to risk loosing my data, regardless of the cost. I guess this sums it up. Any help is greatly appreciated. My DVD's are all boxed up and I'm about to put the Pioneer carousels on the market. I figure I'll burn the DVD's to hard drive as I watch them going forward, so this will be a gradual transition.
