[mythtv-users] Troubles with Irtrans VFD

Fri Apr 18 14:41:42 UTC 2008

So I have compared the logs of Mythlcdserver fro the following three
situations:

A) Start mythfrontend (as normal)
C) Start mythlcdserver then start mythfrontend
D) Start mythlcdserver then start mythfrontend then "reload" frontend by
running through the Setup/Appearances screens

It looks like the following two lines do not appear when starting
mythfrontend in all three situations.

MythSocket(8bf7870:9): socket is readable
MythSocket(8bf7870:9): cb->readyRead()

For situation C: somehow when the frontend reloads after finishing the last
Setup/Appearances page the first thing that happens is that the socket
becomes readable and ready, thus enabling the VFD. It is almost as if
mythfrontend is somehow initially blocking the socket. Perhaps this is
timing related?

Will do some further testing tonight... perhaps start mythfrontend as
normal, kill mythlcdserver pid & start mythlcdserver again manually...see
what happens.

If anybody is having similar problems or has advise (or better yet a
solution lol) please let me know.
