Now that I have 7.1 and this DVD?

I looked on the hcdb and saw nothing regarding DVD players. SuSE must have some belief that DVD players/devices are supported. What should I buy? I remember someone saying there is a difference between DVD data and DVD video. I'm still not clear if that distinction is a hard ware issue. I'd like to buy a DVD that is compatable with SuSE Linux 7.1, and not spend too much on it. Any suggestions? TIA, Steve
