[mythtv-users] Re: DVB summer time
When you view the details of a particular channel in mythsetup, there should be a checkbox that says something like 'use on-air guide'. Just make sure that it's enabled - you also need to make sure that the setting for 'use dvb card on demand' is set to off - i.e. the backend always has access to the dvb card. You might have to restart the backend now. Then it's just a case of waiting - within five mins or so, you're guide data will just magically appear. No need to run mythfilldatabase etc - so take it out of the mythfrontend configuration or any cronjobs that you might have setup. Correct me if I'm wrong.. But disenabling 'use dvb card on demand' causes the dvb card(s) to run hot all the time, and that is not good for a quiet, long lasting system. At least this was the case down 0.15.

I have the same problem, I tried adjusting the timezone back to UTC and clearing the database but it didn't make a difference. I then tried adjusting the TimeOffset setting in the database (XMLTV time offset in the setup program) and that made no difference either. Strange, all I needed to do was change the /etc/localtime to point back to GMT - it looks like the times held in the DB for me are in GMT regardless of what the localtime is set to, which meant that I didn't need to clear out the program table again. As for dvbdate - it seems to work correctly regardless of the timezone settings :) Thanks ___ mythtv-users mailing list mythtv-users@mythtv.org http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users

I use a CVS version from around two months ago and use the DVBDATE
utility from the LinuxTV utilities to set the time.
My cron job ran as normal the morning of the clock change and
everything continued to work perfectly. Running dvbdate --set within
the script that I use to update the EPG and backup the database seems
to work perfectly.

My cron job ran as normal the morning of the clock change and everything continued to work perfectly. Running dvbdate --set within the script that I use to update the EPG and backup the database seems to work perfectly. I am also using dvbdate to set the time on my box. The time is correct, it's only the time of the shows in the EPG that are out by an hour. Are you are using mythfilldatabase to fill the EPG? The issue I am talking about only effects the built in function to pull the EPG data from the the digital TV signal (DVB). mythfilldatabase has it's own correction for daylight saving that is seperate from the built in stuff (and did previously have errors occording to google but I think they are all fixed now). JD -- There are two ways of constructing a software design. One way is to make it so simple that there are obviously no deficiencies and the other way is to make it so complicated that there are no obvious deficiancies. - C. A. R.
