<p class=MsoNormal>I had a couple of earlier threads dealing with channel
changers for Scientific Atlanta STBs. I thought I would post some follow
up info here for anyone else trying to get these boxes to work. My
initial problem was that nothing would work with the SA4240HDC. <o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I gave up and swapped boxes between MythTV and another set I
had in my bedroom, a SA3250HD. The sa3250ch.c program provided with the
myth distro worked with this box. However I had a problem that on reboot
it would not function until I unplugged and replugged the firewire cable (thus
resetting the firewire bus). <o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I posted on the linux-1394-users list about this. Stefan
Richter replied and said “This is strange. From a quick look at
sa3250ch.c, it seems to contain<br>
all necessary code to ensure that it directs its request to the right target.
So I'm not sure what is going wrong.” But as a workaround he
suggested using an app called firecontrol (which can be installed via yum) to do
a software firewire bus reset instead of mechanically unplugging/replugging the
cable. I pass this along in case anyone has the same problem and wants to
try this in a startup script or something.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Meanwhile Christian Szpilfogel pointed me to this software <a
href="https://wiki.ubuntu.com/majoridiot?action=AttachFile&do=view&target=mythchanger.10f.beta.tar">https://wiki.ubuntu.com/majoridiot?action=AttachFile&do=view&target=mythchanger.10f.beta.tar</a>
as an option for the SA4240HDC. I just tried this and it works great, so
now I have re-swapped the STBs and don’t have to worry about the bus
reset thing. <o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I thought I would pass on some Fedora specific info about
the required libraries to supplement the README that comes with the software
(which is specific to Ubuntu, I think).<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>The README says you need to install a package called
build-essential, but that package is not available for Fedora. For the same
functionality just make sure you have packages make and gcc installed.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>The README also lists three libraries that need to be
installed. On Fedora repositories these are named <o:p></o:p></p>
