I'm a complete newbie to XBMC. I recently ripped all my SACD and DVD-Audio discs to a file server. The convenience of playing my favorite tracks is tremendous. So I thought I would try the same with my concert DVD & Blu-Rays. This is what brought me to XBMC. But I'm not sure which format is best - MKV or ISO? What are the pro's and con's or each type of structure. I'm leaning towards ISO since it's one simple file rather than the directory tree of the MKV's (maybe I'm doing it wrong?).

Any advice is appreciated by a newbie who's about to start ripping concert videos.
