EPG time data in germany - about 3 minutes at the end of each recording is lost

Hi,

I am using MythTV with DVB-S in germany (Astra 19.2E).

But whatever I record, I am losing about 2-3 minutes of the end of each
broadcast unless I tell MythTV to add some minutes to the end. But this
is annoying and I am having trouble if I want to record multiple shows
directly after each other, even if on the same channel.

Is the EPG data not accurate? The clock in the PC is synchronized with
an internet time server...

Once, in analogue TV, there was a technique that transmitted a code as
soon as a movie started... I think it was called VPS?! Is it really the
case that today one must rely on time instead of having a live-signal
that can tell mythTv how long the recording has to be? I consider this
stone-age... Or did I miss something essential?

Kind Regards
Thorsten

Version 0.21 of Mythtv is supposed to fix that, at least that version
should be able to record multiple channels from same bouquet, about
overlapping recordings maybe not.

DVB has what is called 'running status', most providers dont send it
correctly, in Germany providers like ARD use VPS, AFAIK Mythtv does
not use VPS, OTOH VDR uses German VPS.

0.21 has an option to record pass the end of a recording. I think it's in
the setup somewhere.

This is not the same as adding a few minutes onto the schedule, as it will
not record past the end if another recording is due to start on a different
channel.

It's in 'General' setting in the frontend...

explains it better than I do. :)

We used to have that in the UK too, it was called PDC (probably the same
thing.), really useful when used correctly, but most broadcasters,
especially commercial ones, seemed to flag the end of programmes about 2
minutes into the next one, which made back to back recordings on different
channels annoying.
