Hello, <br>
<br>
I have a saa7134 video tuner card (Terratec 400) the picture quality is
great and the sound works but there is one very annoying issue:<br>
after changing a channel you hear a loud noise / hiss during the first
seconds after the sound frequency is correctly found everything is ok.<br>
<br>
This problem has been worked around in some other programs like e.g.
TvTime by setting the volume to 0 the first seconds and then the volume
is faded in to the normal level. I haven't seen such an option in MythTv<br>
<br>
What I would like to do is to create a change channel script that sets
the volume to 0, changes channel and after 3 seconds e.g. restores the
level. An example of such a script has been created and can be seen at <br>

<br>
But my problem is that I have Fedora Core 4 running (Jarod Wilson's
howto) and I don't have v4l tools installed so I have no v4lctl to
change channels. I can only find Suse 10 rpms to install v4l tools, is
this gonna work on Fedora Core 4 ??<br>
<br>
My questions:<br>
- is there an option in MythTv to fade in after changing channels? If not:<br>
- how can I change channels from a command line, is there an MythTv API
I can 'talk' to? or do I need v4lctl, are there alternatives?<br>
<br>
Suggestions, hints etc are welcome!<br>
thank you,<br>
<br>
