Well i haven't ripped either so its flexible, i'd need some arranged bandwidth support before i start ripping.
402mb or 744mb an episode would be appropriate in this day and age, for farscape i'd be more 744mb inclined. If that's what people want, there's 4 series with about 22 episodes in each:
4x22x744mb = 65472 mb = 63 GB
/ 4.38 = ~ 14 DVDrs
4x22x402mb = 35376 mb = 34.55GB / 4.38 = ~ 8 DVDrs
The problem with 402mb is the lower gain you'd get over existing series.
The diviser between DVD-r breaks is the difficulty in choosing a filesize.
Twin peaks i don't recall the number of episodes off hand.
I mean if your wanting angel and would be willing to upload to newsgroups, i can provide access to them (they are 744mb). pm me if so.
