[mythtv-users] Hiding recording groups from DLNA front-ends?

[Phil Linttell]

I understand that there is nothing that allows any filtering of what 
recordings are made visible to DLNA front-ends (e.g., PS3).   If I 
wanted to simply hide all recordings in a specific recording group from 
any DNLA front-ends, is there a relatively simple change I could make to 
source in trunk that would do this?  Which source file should I be 
looking in?
