EPG dumping alongside recording (replacing EPGFROMDVB)

[GoogleCodeExporter]

DVBE4SAGE "sees" all the data needed for dumping EPG, so it should do so
upon request.

i think it's should do epg dump without a request, every specified time frame 
(like 
30min/60min)

also the good idea from same mechanism to send EMM to card/md-api.

What is the expected behavior when epgfromdvb collides with dvbe4sage?
Could it be that this collision causes my SageTV server to stop decoding every
morning, until I reset?

These two shouldn't collide. When one program locks a tuner and another one 
tries to
access it, it can mess up the first one. So you should make an effort to avoid 
this
from happening (ideally, using a dedicated tuner for EPGFROMDVB).
When this request is resolved, these situations won't happen anymore.

Thanks. I ordered another DVB-S tuner (not S2 - so pretty cheap). Until it 
arrives, 
will disable one of the existing tuners in dvbe4sage.
Maybe a locking mechanism for tuner access, with preemptive "abort" command 
from 
dvbe4sage to epg would work?
this way we give dvbe4sage priority, and run epg more often. Then, signal that 
dvbe4sage is using a tuner through simple files (semaphore :-( ), and have epg 
check 
for the files before starting. If we limit this system to 1 epg running 
concurrently, maybe changes can be kept to a minimum, and the two processes can 
also 
be kept rather isolated.
