Multiple Video Sources can specify the same XMLTV grabber/configuration, 
however, MythTV does nothing to "cache" the results for XMLTV*, so it 
may, effectively, just hit the site twice (unless the grabber, itself, 
or some other XMLTV thing does the caching).  If that's the case for 
your grabber, the best approach is to configure an external script that 
does the caching for you.

Someone who knows XMLTV better than I may be able to give you more 
information.  As a matter of fact, I wouldn't be surprised if there's 
some "standard" XMLTV caching script or capability.

*TTBOMK, MythTV only caches Schedules Direct listings data so that it 
can be reused by multiple Video Sources without fetching, again, and 
does not do the same for XMLTV data.  However, we would be happy to have 
a patch to enable XMLTV data caching (as a matter of fact, if I get my 
way--and switch MythTV to use XMLTV for Schedules Direct users, 
too--we'll need it so we don't "lose" capability).
