I proposed this same patch previously, but it was suggested to instead of the check for transfer mode to just change the Receiving() to Receiving(true). I didn't see any caveats back then, so I agreed. Unfortunately, that resulted in problems with situations that you describe. However, this original version of the patch does explicitely check for a device in transfer-mode, and does not care about osdteletext receivers. What could happen is that this would match the transfer modes whose receiverdevice() is the primary device itself (some situations related to the ca or ac3, I guess), thus starting the new receiver in the primary device, which could cause side-effects if the card's bandwidth is not wide enough. However, even without this patch, when a recording is already taking place on the primary device, this rule matches and another recording could be started on the primary device. I don't know if we should be preventing these from happening, but if we do, I think we could make the rule as imp |= !device[i]->Receiving() && (device[i] != cTransferControl::ReceiverDevice() || device[i]->IsPrimaryDevice()) || ndr // prevents matching local-transfer-moded primary-device or imp |= !device[i]->Receiving() && device[i] != cTransferControl::ReceiverDevice() || device[i]->IsPrimaryDevice() || ndr // addidtionally prevents matching recording primary-devices -- Anssi Hannula _______________________________________________ vdr mailing list firstname.lastname@example.org http://www.linuxtv.org/cgi-bin/mailman/listinfo/vdr
