To answer your questions:
- Because the new Slingboxes do not have coaxial input, the only way you could view the Slingbox independently from the attached TV would be if the set-top box has what is known as a "dual-tuner". A dual-tuner is a set-top box feature which allows for two separate outputs to two separate devices from the same set-top box. These separate outputs allow for the Slingbox and TV to be viewing channels independently from each other at the same time.
2. The USB drive on the Slingbox 500/SlingTV does not allow you to record DVR content to a USB storage-device. The USB drive on the Slingbox 500/SlingTV is for the feature known as "My Media". For more information on the My Media feature, check out the links below:
