Actually, the recording parameters are "recording" characteristics
rather than playback characteristics...

you show decide what your default configuration is. For example,
I'll assume that you have a master and two slaves with 1500 mhz
and two slaves with 300mhz. Probably not the case but...
Choose "Software Encoders" (assuming that you are using all bttv
cards) and set the four profiles including "Live TV" to what works
for your 1500mhz machines. This will then be the defaults for all
5 machines but you have two slow slaves that can't handle it. Next
choose "(Create new profile group)". Enter a unique group name
possibly based on the hostname ("X"? ;-) of the first slower slave.
Choose the card type ("Standard V4L....") and hostname ("X"). This
will create a new set of profiles that will be used for "X" only.
Do the same for "Y".
When you schedule a show to use "High Quality", if it records on
"A", "B", or "C" it will use the default "High Quality" settings
but if it is to be recorded on "X" or "Y" it will record with the
"High Quality" settings of the custom profile group that you
created for that host. Same for live TV. It will use the appropriate
"Live TV" profile for the backend recorder(!) that is recording
regardless of which frontend is displaying LiveTV (not necessarily
the same host).
Or more succinctly: What Isaac said ;-).
