Your system is quite demanding, at least in the storage sector. I can say that broadcast quality uncompressed video runs at a very high bit-rate (about 235Mbps, or 105.8G/hr). That's like a DVD-drive running at 24X. Because the amount of data and its rate is enormous, I would recommend some kind of compression, even if it's mild, say 3:1. The DV encoder on digital camcorders take it down to 5:1, with decent quality.
Anyway I'd definitely go with a large RAID (at least 5 HDDs, 200gb min). Use SCSI HDDs if u can afford, otherwise use SATA. If there's a lot of programs to store, consider getting multiple servers. You'll be able to distribute the storage and load across them.
From this point on, I'm not sure if this would be suitable.
Have at least a gig of RAM and a fast (well standard now) 3GHz+ processor. You certainly need something that plays videos fast and smooth. Gigabit ethernet might also help.
And to your scheduling, would cron jobs help ??? If there's multiple servers, then a single "configuration server" should control the others.
Also how are you going to output the video? Through a TV-out port? DVI? Or a special broadcast connection?
EDIT: On second thoughts, a 3GHz processor isn't really needed. 1.5GHz+ would be more reasonable. However, if high-definition video is involved then you will need much higher specs.
