After the problem started downloading again, my global DL dropped to ~8K (yeah, GLOBAL). When it's working correctly, and I have the globel UL set right, I can get upwards of ~150K Global DL.

Well, that could very well be my problem - I'm seeding two shows, downloading three - But I still can't figure out why 27K worked for awhile, and now (after playing around), the highest I can go is 12-15K.
