Sorry, I was a bit unclear there, the syslog gap means that there is
still a large difference between event change and pid change.

Hmm... I didn't record the program, but my logs say, that

Apr  9 22:05:19 localhost vdr[4722]: channel 1 (YLE TV1) event 22:05
                                     'Frasier' status 4
Apr  9 22:05:25 localhost vdr[4722]: channel 1: ALang
                                     changed bud don't care

but I can't confirm if the possible gap would have been inside the
program or not here, as the modification prevents pid change. The latter
line is a (slightly typo'ed) log message I added along with the
modification, so it corresponds to the "changing" log message. The
PMT_SCAN_TIMEOUT is set to 1. Without the modification and the
timeout=1, I seem to still get differences of ~5 seconds, so the
"wrinkle" appears well inside the program (tested it again today).
