Multi room suggestions - DirecTV DVR

For Multi room suggestions, relating to DirecTV DVRs and receivers. Like the Multi-Room. Here are suggestions:
1. In playlist have a column showing room source.
2. Allow sorting of playlist by room, then the other sort options
3. Buffer the remoteroom so the backspace and forward space isn't so choppy.
4. Refresh the checking of other room DVR's that are part of multi room. If a DVR gets temporarily disconnected from network the only way I can get it to be seen again is to reboot it.

Great progress.
