Hi
My system has hvr-1300 (adapter0 connected terrestrial antenna for for
dvb-t) and hvr-4000 (adapter1 connected to satellite dish for dvb-s, dvb-t
antenna unconnected.)
Whether I use just vdr-1.4.7, 1.6.0, 1.6.0-2 or 1.7.0 with or without any
plugin, I have noticed that the dvb-t playback usually breaks about after
5-10 minutes and only reliable way to retune is to shutdown the vdr
(ctrl-c for runvdr script and) and then restart it again. I have observed
same behaviour every time over many days and for vdr-1.6.0 the
/var/log/user.log shows always a following types of lines to be repeated.

After googling some vdr discussions I found that somebody had a patch for
disabling the epc scan due to similar types of problems. Therefore I went
to configuration option
setup/EPG/EPG Scan timeout (h)
and changed it's value from 5 to 0. After that my vdr has now worked 15
hours without any problem. What does this EPG scan timeout do and should
it be disabled by default if the system has dvb-t channels configured?
Or is somebody seeing this problem or having a patch for
fixing it?
If I am using vdr for watching the dvb-s channels, things will work
without problems even if this epg scan timeout is set.
With vdr-1.7.0 I have used the liplianis multiproto tree and vdr 1.6.0 I
have used with new dvb-v4l, S2 (http://linuxtv.org/hg/~stoth/s2/) and
s2-mfe trees. (drivers from s2 and s2-mfe repositories works for me with
vdr-1.6.0 when not trying S2 as the driver api is backward compatible)
In addition I have tested with kaffeine with same drivers and there the
system worked hours without losing the lock to dvb-t channel.
