The two units you mention are the same thing. The full, correct model name is the DVD-3910, and it is a universal player.
The 3910 has not been on the market for terribly long, so it's a bit early in the model life to judge its reliability. I have been using my 3910 for about 9 months and it's worked fine.
Before you decide to send your 3910 off for a "mod", spend a month or two listening to it first. It's got excellent sound quality, and you may find that you'd prefer to spend your money on more SACD's, or to upgrade some other item in your system.
Although you didn't ask for an opinion on the subject of "mod's", I am of the school that believes that mods are not a particularly good investment. For the cost of an expensive mod plus the price of the equipment, I think you are usually better off to simply buy a much better piece of gear. For the cost of the basic 3910, plus one of the $1500-2000 mod's, you can instead buy the Denon 5910, or a comparable unit by Marantz, Sony, etc.
