It doesn't have to -- it depends on the software you're using. Usually *some* kind of compression is used, though, because otherwise the disk space and disk bandwidth requirements become unwieldy. Even professional digital video systems generally use some kind of compression at every step of the process. If you're talking specifically about MythTV, yes, there's always some form of compression. A PVR without compression wouldn't be able to record a useful amount of material. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe. Trouble? Contact [EMAIL PROTECTED]

buying TV card
I'm in the market for a TV card for my etch system. I'd prefer pci hardware. I don't really care about actually watching tv programs on my computer, I just want to record shows, edit in kino, then burn to dvd for viewing later on a stand alone player. Ideally, I would be able to program shows to record like I do on a vcr. So, anyone have any ideas on supported tv cards for etch? thanks much, scott -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe. Trouble? Contact [EMAIL PROTECTED]
