Ok, this isn't a totally newbie-esque question, I hope.
At work, we're looking to buy 2-4 DVD burners to have them around a computer lab for graduate students. We don't expect them to get a ton of use, but as faculty members start moving towards a more 'multimedia' experience, we are expecting creation of DVDs might become more of an issue. (I'm not even thinking about the hardware/software video editing portion yet)
I'm just trying to figure out what burners are very reliable, able to handle poor treatment (like shoving in the door to close the tray on a repeated basis), and most importantly, able to handle a wide variety of crappy media. No matter how much you try to teach the students, they bring in the worst possible blank CD-Rs/CD-RWs, so I can imagine DVDs will be even worse. (I'm expecting to see a lot of Memorex) Plus, we won't know if they're bringing in +Rs or -Rs so it needs to be able to handle both fairly well...
I know in the past the Pioneers have been pretty good at burning low-quality DVD-Rs, but their +R performance isn't too hot. I have been thinking NEC or Benq; Plextor is a bit too pricy (not to mention to wild variances in 716A quality, and I'm pissed at their Linux stand). I've been leaning towards the Benq but it's harder to find from our normal suppliers.
Any comments? Anyone have experience supporting DVD burning in a lab?
