Have the newest Motorola HD-PVR. Want the option to record some programs in SD because HD requires and uses a lot of hard drive space on my PVR. How can I do this?
DCX3510 you can't, to put it simply
Hey there marksmobile
The HD Guide (used on the DCX3510) uses a feature called Auto HD (AKA HD Overlay) which replaces the SD feed of a channel with its HD feed if it is available. This feature is implemented with the interest of making HD content more easily accessible, but unfortunately it does get rid of the ability to watch or record SD instead of HD if one prefers to do so.
More info on this can be found here: HD Guide - HD Grouping
