depending on the distributor of the DVD, it may be VERY wise to use DVD decrypter before you encode the DVD. It is useful for splitting eps that are in 1 long chain and for removing blank cells which contain nothing but cause audio desync when encoded (Funimation is notoriorus for using this). It isn't that simple but if works. @flyinPenguin: 7 GB DVD rip is pretty much losless and taking the MPEG-2 video and putting it, the audio tracks, and subtitle tracks in a .mkv. 30 GB BD rip is the same although there MAY be some compression used. I could probably fit a series (or 13 epsiodes) in that same 7 GB depending on the size and maybe 13+ in that same 30 GB BD rip just based on encode settings I use. I second megui however you'll want to use dgindex to make a .d2v, load that in the .avs creator, and when going to do the anaylsis, tick 'source is anime' before click anyalsis.
