/Root/Application dvrRecorderControlSuffixes String * Can be an empty value, a "*", or a comma-separated list of name suffixes such as _source, _720p, _360p, _240p, _160p. The returned value is controlled by the settings of dvrRecorderControlMatchAllow and dvrRecorderControlNoMatchAllow. The suffixes are compared with the end of the stream name. (default: *)
/Root/Application dvrRecorderControlMatchAllow Boolean true Controls the action taken when a match is found in the list of suffixes. If set to true, then the suffix list is is treated as a list of stream name suffixes that will be recorded. If set to false, then the suffix list is treated as a list of stream name suffixes that will not be recorded. If the list is a *, then this setting will be returned automatically. (default: true)
/Root/Application dvrRecorderControlNoMatchAllow Boolean false Controls the action taken when no match can be found. If the list is empty, then this setting will be returned automatically. (default: false)
