I'm new to this mailing list, so excuse me if I'm posting to the wrong place. I'm using a DiBcom USB module on an Ubuntu 11.04 host. The v4l-dvb drivers were downloaded via git and built on June 13, 2012. Basically, I can watch DVB-T by running mplayer (version SVN-r35003-4.5.2); however, if I ran tzap before launching mplayer, then I would get a series of "dvb_streaming_read, attempt N. 6 failed with errno 0 when reading 2048 bytes" failure messages. Then I must unplug the DiBcom USB tuner and plug it in again so that I could relaunch mplayer to tune to a DVB-T channel. The console output of running mplayer as well as tzap is as attached below. Has anyone experienced the same problem? ========================================================================== hying@hying-VT3410-8595CMB:~$ gmplayer dvb://CTS MPlayer SVN-r35003-4.5.2 (C) 2000-2012 MPlayer Team Playing dvb://CTS. dvb_tune Freq: 593000000 TS file format detected.
