I can't find the US-based one (I remember there being one) but I found a Finnish court decision ruling that CSS is "ineffective" as a technological measure and therefore not covered by the part of the DMCA/EUCD that disallows "circumvention of effective technological measures".

My understanding was that it was the inclusion of libdvdcss that was the problem, as this is a tool for circumventing encryption and/or defeating copy protection (regardless of whether you then go on to make a copy).
There are probably arguments that could be made either way, but it wasn't something we felt comfortable distributing as an institution.
In answer to the original question, most drives are supplied with a license for something capable of dvd playback (usually powerdvd), and we have confirmed with our PC supplier that we are licensed to use that on hardware that we have purchased with a DVD drive, so we install that instead. The version we were supplied with is restricted to devices from that manufacturer and does a BIOS check at install time.
