Hello,
With VDR 1.7.9 i often notice that VDR switches the live TV to a different receiver card, when a timer starts recording, although the second card is available. This causes a short interrupt in live TV.
My system has two DVB cards, an old FF and a Tevii S470, and an eHD.
Sample situation 1: the only activity is live TV on ZDF. Now a timer starts recording from RTL 2, which interrupts the live program for a short moment.
Sample situation 2: the only activity is live TV on RTL. Now a timer starts recording from RTL 2. Nothing happens, because VDR correctly shares the transponder with live TV.
I would understand when VDR switches live TV from the DVB-S2 card to the DVB-S card when it needs to tune a different transponder for a DVB-S2 recording, but since it can do DVB-S recordings from any card, there is no reason to switch live TV for such recordings.

When recording, VDR tries to preserve devices that provide multiple delivery systems:
imp <<= 2; imp |= GetClippedNumProvidedSystems(2, device[i]) - 1; // avoid cards which support multiple delivery systems
See device.c, cDevice *cDevice::GetDevice(const cChannel *Channel, int Priority, bool LiveView).

Then it would be a good idea to prefer those cards for live view.

But then you would get interrupted if you watch a DVB-S programme and VDR wants to record a DVB-S2 programme ;-)
I guess it won't be that long until most VDRs will only contain DVB-S2 cards, and by then this is obsolete, anyway.
