well i got the following respond from jmichault in another forum:
Apparently, Showtime does not use a format compatible with mhwepg.
mhwepg read the format used by canalsat (fr), cyfra (pl), canalDigitaal (nl) and SkyItalia(it).
otvepg read the format used by TPS (fr).
mhwepg2 read the format used by digital+ (sp).
To know if Showtime uses one of this formats, you can scan the pids presents on the EEPG channel with dvbsnoop :
http://dvbsnoop.sourceforge.net
To know what PIDs are presents :
dvbsnoop -pd 9 -f 24 -s pidscan
The format read by mhwepg uses PIDs 210 and 211.
The format read by mhwepg2 uses PIDs 561, 564 and 566.
The format read by otvepg uses PID 4150.
To know what are the elementary PIDs :
dvbsnoop 17
To show information on the PID xxx :
dvbsnoop xxx
To capture the PID yyy :
dvbsnoop -b yyy
can some one please compile a dreambox hyda friendly version of dvbsnoop so i cant test the EEPG to check what type of epg data it is sending.
