A small problem... I have a 722k. Recently subscribed to Blockbuster and there are a couple movies I wanted to 'stream' with the Dish on Demand feature. Got them started and the streaming/download info came up with the usual, 'This will be available for 29 days' (or some such thing). Anyhow, next day---gone. OK, not a big deal probably a 'glitch'. Did a reboot of my system, downloaded again yesterday, message 'Available for 29 days' and again this morning - nothing. Is this a glitch on my receiver or with the Dish software?
