Are you budget minded? Are you running high end electronics? Do you listen to SACD and DVDA? I sold my 3910 and couldn't tell the diff with a new Pioneer DV48A for $99! Granted, it runs a little slower, but I don't use mine that much.......one SD movie a week, and the ever rarer HiRez disc... If you are budget minded, the 2910 would do everything you could want, the 3910 would be a good machine if you are a tekkie or looking to launch a space shuttle mission from your living room. If you want the latest greatest almost universal player (no bluray), get the xx30CI series. At this stage, I think unless you have a large collection of HiRes music you listen to often, get a blu ray player. IMHO.
