Thanks Fyron! Now perhaps I should start looking for a DVD player to begin with. Yes, I seem to have expected the DVD to play without requiring an additional player; how naive of me.
You just need a DVD-ROM drive. You can find one for 20 bucks US... They are pretty cheap these days, what with DVD burners having come down in price so much. Most of them come packaged with a software player... If not, there are plenty of free programs out there that work great. Just ask.
