I've been confused on the meaning of DVB until recently, so I'll try to help out. If someone notices that I didn't get it quite right, please jump in and correct me.

ATSC is the American standard for broadcasting digital television--think of it as the digital version of NTSC. Europe uses a different standard for digital TV that is commonly known as DVB (even though ATSC is a form of digital video broadcasting). And the confusion is only beginning. Linux has two sets of driver interfaces for video. There's the video4linux drivers. That's what most video cards work with, including the official drivers for the HD-x000 cards. There's also the DVB driver interface. That's what one unofficial HD-3000 driver and the regular Air2PC drivers use. The linux driver model that is used for the card doesn't depend on the broadcasting standard. So if you're living in the USA, and you want to capture broadcast digital video, you need an ATSC tuner card. If it supports ATSC, it's what you want. Well, if you want to use it with MythTV, then you need Linux drivers that MythTV supports. So you want the HD-3000 or the Air2PC card. --PC
