Suggestions for a DVD jukebox HTPC

The info that I found was saying mainly that when multiple VOB files were used the unit would lock up. I don't typically rip to VOBs though, so I don't know when/if that's an issue.

I was a shrink guy, but now I'm using clone. I usually rip to iso and just mount those or burn them depending on whether I rip at work or at home.

My main use is just a DVD jukebox for movies I have yet to see. I rent them, rip them, watch them, and throw away the file/copy. Honestly. I just don't care to watch a movie more than once so I don't have a library of movies (ok I have 10 or so, but who can live without Office Space on the shelf?)

I only have plan and need for 50 gigs or so since I usually don't have more than 10 waiting in line to watch, and I rarely actually watch the special features or listen to commentary unless it's super special.
