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.

Oct 14 02:36:25 tinka vdr: [1965] logger 0 filter thread ended (pid=1919, tid=1965) Oct 14 02:36:58 tinka vdr: [1928] changing pids of channel 819 from 163+163:92:0:41 to 163+163:92:65=ell:41 Oct 14 02:37:19 tinka vdr: [1924] frontend 0 lost lock on channel 1, tp 546 Oct 14 02:37:19 tinka vdr: [1924] frontend 0 regained lock on channel 1, tp 546 Oct 14 02:37:21 tinka vdr: [1924] frontend 0 lost lock on channel 1, tp 546 Oct 14 02:37:22 tinka vdr: [1924] frontend 0 regained lock on channel 1, tp 546 Oct 14 02:37:23 tinka vdr: [1924] frontend 0 lost lock on channel 1, tp 546 Oct 14 02:37:23 tinka vdr: [1924] frontend 0 regained lock on channel 1, tp 546

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.
