The signal seems to die a few seconds after tuning. + + It's not a bug, it's a feature. Because the frontends have + significant power requirements (and hence get very hot), they + are powered down if they are unused (i.e. if the frontend device + is closed). The dvb-core.o module paramter "dvb_shutdown_timeout" + allow you to change the timeout (default 5 seconds). Setting the + timeout to 0 disables the timeout feature. + +2. How can I watch TV? + + The driver distribution includes some simple utilities which + are mainly intended for testing and to demonstrate how the + DVB API works. + + Depending on whether you have a DVB-S, DVB-C or DVB-T card, use + apps/szap/szap, czap or tzap. You must supply a channel list + in ~/.[sct]zap/channels.conf. If you are lucky you can just copy + one of the supplied channel lists, or you can create a new one + by running apps/scan/scan. If you run scan on an unknown network + you might have to supply some start data in apps/scan/initial.h. + + If you have a card with a built-in hardware MPEG-decoder the + drivers create a video4linux device (/dev/v4l/video0) which + you can use to watch TV with any v4l application. xawtv is known + to work. Note that you cannot change channels with xawtv, you + have to zap using [sct]zap. If you want a nice application for + TV watching and record/playback, have a look at VDR. + + If your card does not have a hardware MPEG decoder you need + a software MPEG decoder. Mplayer or xine are known to work. + Newsflash: MythTV also has DVB support now. + Note: Only very recent versions of Mplayer and xine can decode. + MPEG2 transport streams (TS) directly. Then, run + '[sct]zap channelname -r' in one xterm, and keep it running, + and start 'mplayer - < /dev/dvb/adapter0/dvr0' or + 'xine stdin://mpeg2 < /dev/dvb/adapter0/dvr0' in a second xterm. + That's all far from perfect, but it seems no one has written + a nice DVB application which includes a builtin software MPEG + decoder yet. + + Newsflash: Newest xine directly supports DVB. Just copy your + channels.conf to ~/.xine and start 'xine dvb://', or select + the DVB button in the xine GUI. Channel switching works using the + numpad pgup/pgdown (NP9 / NP3) keys to scroll through the channel osd + menu and pressing numpad-enter to switch to the selected channel. + + Note: Older versions of xine and mplayer understand MPEG program + streams (PS) only, and can be used in conjunction with the + ts2ps tool from the Metzler Brother's dvb-mpegtools package. + +3.
