Greeting
Has a USB TV card Astrometa DVB-T2 / C.Iz Serbia alone.
My problem is that when she was a version 7.11.0 progdvb then when scanning program DVB-C with multiplex Serbia located 208 channels.Sa version 7.12.03 and with the same multiplex Serbia is 108 channels .Da mention it happens from software version 7.11 .0 and all subsequent versions until 7.12.03.
Up to version 7.11.0 was no problem with the scanning channels. What can be problem.Thanks in advance for your reply
