Usually I am looking TV with vlc and use a channels.conf with 12 channels, of which each four use the same frequency: 538 MHz, 594 MHz and 618 MHz. I am able to switch to and between the 4 channels of the first frequency-set on 538 Mhz, but the other frequencies don't work. I tried the kernel-images 3.9 and 3.10 from the ubuntu mainline kernelpage, but found the same misbehaviour as described above. Maybe the signal of this channels is too weak. However, I can't remember, ever to have got a signal. Also, the device and all channels worked perfectly with the older 3.5-kernel which I've used before Ubuntu 13.04 switched to version 3.8, and a driver I found on [ https://github.com/valtri/DVB-Realtek-RTL2832U-2.2.2-10tuner-mod_kernel-3.0.0 ]. I used the same hardware and software setup, the only difference was the kernel and the driver. So, as I hope, that it is a driver problem (and my antenna strong enough), maybe the reason for my problem can be found in the difference between the two driver sources. I gathered some information from userspace as I didn't know how to debug this problem otherwise: Under [8.] I attached - the channels.conf - the dmesg output - the usb device information, - the output of `tzap` switching to the 3 different frequencies and - the output of `dvbsnoop -s feinfo` while watching the channel and after plugging in the device, all sorted by kernelversion. Please give me some advice, if I can provide other informations which help. Thanks in advance, Jan Sieber-Taegert.
