This is also worth a look: http://ivtvdriver.org/index.php/Main_Page The driver has been in such a rapid state of development that any documentation would quickly be out of date. It is considerably more mature lately. The mythtv mailing list archives are also a very good source of knowledge. I would say that a very big percentage of people using these cards under linux do so in a mythtv box.

There is a delay for buffering or processing or something inherent in the pvr card. There is no such delay through the sound card. I suppose the card could be broken. Sometimes they are. Any chance of taking it back to the shop and asking for another one? Or *cough* trying it in windows? I also wonder whether you should try either the mythtv-users list or the ivtv-dev mailing lists.

It doesn't have a input for audio and no internal mixer, so I have to record the sound directly from the soundcard. I use menconder to do just that: mencoder tv:// -tv driver=v4l2:device=/dev/video0:input=3:width=640:height=480:alsa -oac mp3lame alsa -ovc lavc -lavcopts vcodec=mpeg4:vbitrate=8800:vme=3 -o outfile.avi I'll try something like that.

That ioctl failure doesn't seem to be a permission problem. The relevant devices all have group video rw permissions and I am member of video. The man page for mencoder is quite undertandable, if you want to customize the parameters. Not really. I think that man page is a big mess. ;-) Though one can find one's way around in it with tons of time.

Hello Uwe, In my experienes, you need to build a 'mixing studio' or at least a very simple A/V mixing system. There are too many A/V tools to use. I'd first look at the MoBo book and see what onboard hardware you have plus 'lspci' -v and 'lshw'. Using the core mobo chips is usually the most straightforward. Also look at what sound cards you have. Then 'eix keyword' using mixer, audio, jack, alsa etc to discover the various packages and try them out. Also use google to search for keywords + audio chips where audio chips are the actual chips you find on your hardware. 'kmix' is a quick and simple mixer that often provides control over the various audio chips. You'll also have to rebuild your kernel many times to find the right combo of drivers to compile in and/or load as modules. Often the various audio chip drivers conflict at the kernel, udev or application level. There is no 'silver bullet' to build a mixer/mux for A/V, in my experience. It all depends on what you need. Moving over old movies, one of your greatest challenges will be keeping the audio and video synchronized over the duration of the recorded stream. hth, James this is all completely irrelevant to the question. The PVR-150 muxes the audio and video into an mpeg stream.
