If you're having problems with dvbv5-zap too, then indeed it is a hardware problem. There are some alternatives: 1) bad antenna/antenna cabling. Usually PC devices require a stronger/better signal than normal TV sets. So, even if you have a good signal at TV, you may not have a good enough signal for those cheap USB sticks; 2) it could indeed be a broken USB stick that it is starting to fail; 3) If you're using hardware like Raspberry Pi, it could be power problem at USB. There are known problems with USB hardware on some RPi devices that cause the device to restart multiple times. Also, you need very strong power supply, in order to give enough power to RPi3 and still have at least 500 mW for the USB stick, without dropping voltage. The dvbv5-zap has a monitoring mode (-m). It runs the device on "all-pid" mode (just like -P) and checks if there are broken frames, counting them. I suggest you to run it for some time on this mode and see what happens. -- You are receiving this mail because: You are watching all bug changes.
