I did not know that. Though 5900 "might" be fast enough to record 1 or 
two shows at the same time, often when new seasons start, you get 3 or 4 
on at the same time to check out. With 5 ATSC tunners, VDR has maxed out 
recording slots because of start/stop overlap. I'm sure I have had up to 
4 recordings going at once.

I'm glad you mentioned the speed issue. I am aiming for a 1TB drive 
which would end up replacing 2 of the seagate 500GB drives making up 1 
side of both arrays. 1GB is proven to be plenty of space. Even when I 
saved a bunch of shows for a month for my dad when he went on a month 
vacations, I I still had room, though it came close. This puts the 
search in a little cheaper drive range with more options to.
