That is it... ^^
I don' t download rm unless its the only choice. General speaking, avi has much higher picture quality than rm. (also the size matters)
If you pay a little attention, you will find every translation group starts releasing high quality avi file. (DVDrip at 1000 ~ 1300K) Some version even include 5.1 soundtrack. (DMHY: Sentoui Yuzukisa)
HDD is not so expansive these days... It is about 1 GB/US Dollar. Of course, CD-R is much cheaper. (about 6 GB/US Dollar)
POPGO/DMHY members are anime fans & we want the highest possible quality as possible... (image watching it in full screen mode on your monitor.... ^^ )
If you want to watch anime in full screen mode, you need at least 900K to get near TV quality. Most rm is sampled at 500k or less...
By the way, if you REALLY want rm files, you might want to give it a try on
