If I was wanting to create some health videos and not knowing what any given person would have as a player, would it be wise to have a burner that would do any format like the drx500ul? or would it be smarter to find a company that presses the video onto the disc as retail movies do? I have the matshita lf-d311 (I think it's the panasonic) and it burns to dvd-r. I don't care about the dvd-ram or at least I don't know why you'd want one.
