EPG updates overlapping and overwriting

[sub]

Upgraded to 1.5.28. Seeing many duplicated recordings sometimes using 4 tuners to record 4 copies of the same show simultaneously.

If you hit 'update EPG' does the problem go away? It should.

The duplicates in the TV Guide are much reduced. The small number of remaining duplicates appear to have identical times. I find them only because it takes 2 clicks to jump over them.

Pending recordings is still broken. I see several examples of the same show being recorded multiple times with a small variation in start times. I have checked the TV Guide and it does not show duplicates for these shows. The duplication appears to be in the recordings only.

Let me know if you need me to provide data.

damn... getting dupes again. and triples too. appears to be where adjusted times put thru fm channels to some extent anyway. Anything I can provide that will assist?

If you hit 'update EPG' do you still see any duplicates? or do they appear later, after watching live tv?

anecdotally, after watching live TV. When first waking the pc, it looks clean, but then as the DBT detail streams in, the guide gets polluted with some channels with small variations in times everywhere. Im testinig the forced update as I write..

BTW.. Can this be made any quicker?.. its painfully slow waiting 60 secs per channel for the updates to take place/ time out.

That's why I switched to xmltv, much quicker

I trust you have a quality xmltv source in 'Viking territory' .. here in oz I would rate our free xml sources as (lower case) ok , while the pay xmltv sources are reportedly good.. though theyve had their legal issues with copyright challenges in the recent past.. the station data is better in some ways - more complete and is avail on all channels.
I was using xmltv files from oztivo for gbpvr , and may resort again , depending on the outcomes here. The DBT data (if its right) is more accurate as programme times are tweaked and adjusted.

Actually, I'm using DVBGuide app to grab it from the cable and air (that runs in a batch at night when noone is up watching tv), I the merge the five xmltv-files into one which npvr is updated from. Works like a dream and it's free

If you like I can mail you my setup on how I do it.

Oh what the heck, I'll put it here for anyone who wants, the apps are freeware. The batch looks like this

Code:

@echo off
rem
rem     Batch file to capture DVBEPG from Canal Digital Cable and Riks-Tv antenna
rem
rem change to working directory
rem

C:
CD \DVBCollector
rem
rem Get rid of old .xml files
rem
del /Q *.xml
rem
rem Now collect all epg from cable provider, by "cut and try" it is found to be on 394000 MHz, QAM64
rem
dvbguide -fX -aC -c394000 -e1800 -m64QAM -s6950 -oc:\DVBCollector\DVBC-EPG.xml
rem
rem Now there are four dvb-t frequencies transmitting epg for the channels on that mux only
rem so we have to collect from each freq. in turn
rem
dvbguide -fX -aT -c490000 -e1800 -b8 -oc:\DVBCollector\DVBT1-EPG.xml
dvbguide -fX -aT -c586000 -e1800 -b8 -oc:\DVBCollector\DVBT2-EPG.xml
dvbguide -fX -aT -c682000 -e1800 -b8 -oc:\DVBCollector\DVBT3-EPG.xml
dvbguide -fX -aT -c786000 -e1800 -b8 -oc:\DVBCollector\DVBT4-EPG.xml
rem
rem merge the two first temporary epg-files
rem
Xmltvmerge DVBT1-EPG.xml DVBT2-EPG.xml /output:Temp1.xml
rem
rem merge the next two. In theory all files could be merged at once,
rem but that crashes xmltvmerge (possibly because of a bug)
rem
Xmltvmerge DVBT3-EPG.xml DVBT4-EPG.xml /output:Temp2.xml
Xmltvmerge Temp1.xml Temp2.xml /output:DVBT-EPG.xml
rem
rem finally merge all togather
rem
Xmltvmerge DVBC-EPG.xml DVBT-EPG.xml /output:TVGuide.xml
copy TVGuide.xml D:\XMLTV\

If you don't know the frequency you'll have to run DVBGuide manually with the frequencies found in Devices->Setup to find the one that gives you the most epg.

Feel free to use this in any howto or wiki.

The DVB spec says that the broadcaster should transmit all their listings within a 60 second period. So, you could make it shorter, but for a lot of countries this would result in gaps being left in the EPG.
