As Scott Cupp noted here yesterday, SyFy Channel is doing a Green Hornet marathon tomorrow. (Thanks Scott!) I haven't seen any of these episodes in a coon's age, so my VCR will be working all day.
Here in the Pacific Time Zone, the marathon runs from 10am to 11pm. I checked the SyFy site, and they list the same times for Eastern viewers. Do they stagger programming by time zone? Could be. Please don't trust me, though. Check your local listings.
