Hi, I have been ripping my DVD collection over the past week in preparation for getting an AppleTV (I'm waiting till after MacWorld). I have about 55 TS_Folders right now and am planning on ripping them with the HandBrake AppleTV preset in H.264. It just occurred to me that as MPEG4 is being replaced by H.264 as the preferred way to encode, when H.264 is replaced by the next new codec what will happen to all the DVD rips? Will everyone re-rip all their DVD's? I am trying to figure out if I should leave the TS_Folders on my drive or delete them and just keep the smaller H.264 files. Thanks!
