I never said I was concerned about performance. I've been using mythtv
since version .14. I've always used mythvideo this way and it has always
worked great. I happen to have a gigabit network. Storage Groups was
suggested so I'm going to take a look at it when I get a chance.
I also apologize for saying SAN when I meant NAS. Yes, I have a NAS. I
deal with SANs with work, and accidentally said SAN.
If you want to help, I welcome it, but please don't attack me for
misguided conclusions that you have made for some reason.
