I'm looking to make the plunge to Droid now that the new Droid X is announced but I'm still researching. I was looking on the web and I see some software to convert DVD's to formats so that they can be played on the Droid. Can anyone that does this give me an estimate as to how big the file size is when a DVD is converted? I realize that the quality can be changed which will affect the file size, but I'm trying to figure out about how many dvd's I could fit onto a 16gb card. Thanks.
