Sorry to jump in
I get the same run around, with DTV vs Tivo. My issue has been the On Demand not working as designed. Some things work, others do not, and no it is not the Satellite downloads that are the issue. Nor a network issue, everything passes. But it is ridiculous that neither company wants to handle the issue.
