I get the same error with both softdevice and dxr3. The default 5s
TUNER_LOCK_TIMEOUT is also unfortunately sometimes too short for a
terrestial tuner (Hauppauge Nova-T) lock. There could be something in
2.6.x DVB as well which has increased lock time from 2.4.x. I have
increased the timeout in vdr to 8s which seems to fix it.

I agree. For diseqc motors it could be based on motor speed. Correct
lock cannot be done before a turn degree dependent minimum time. It
could happen that e.g. when moving from 13.0E to 28.2E vdr could
temporarily lock to 19.2E and receive whatever channel updates and EPG data.
There is one more thing which could be fixed for motorized dishes. The
EIT scan moves the dish all the time wildly. Some motors are too noisy
(like mine) and may wear mechanically for this. I have added this ugly
hack to eitscan.c to limit scanning to afternoon/evening hours.
...
void cEITScanner::Process(void)
{
struct tm now_tm;
int enablescan;
if ((Setup.EPGScanTimeout || !lastActivity) && Channels.MaxNumber() >
1) { // !lastActivity means a scan was forced
time_t now = time(NULL);
now_tm = *localtime( &now );
if ((now_tm.tm_hour >= 21) || (now_tm.tm_hour <= 14))
enablescan = 0;
else
enablescan = 1;
if ( (now - lastScan > ScanTimeout) && (now - lastActivity >
ActivityTimeout) && (enablescan > 0) ) {

A decent solution for limiting optionally EIT scan should be DVB adapter
specific and the time for allowing scan should be configurable from vdr
setup.
