Channel Scanning From Firewire box?

I have setup a firewire connection to my cable box and it works fairly
well.

There are some oddities - like if I tune into a channel that does not
transmit over firewire, it will kill my firewire connection.

Typically, I have to unload the firewire modules, reload them and then I
would be good to go.

I have my channel listings downloaded via scheduledirect. What I would
like to do at this point though, is remove the channels that do not come
over the firewire. Some of them are fairly odd - like some locals or
the Weather Network.

Does anyone have a scanner or perl script that would step through the
channels and test for a firewire connection? If not, I suppose with
tools out there like firewire_tester and test_mpeg it wouldn't be that
difficult.

Thanks
Norm

I have/had similar firewire issues. Basically for channel control, i
have found it cleanest to:

1. Filter the 'bad' channels from your schedulesdirect account.
2. Delete all the channels from mythtv-setup (channel editor)
3. 'Fetch Channels from Listings Source' from 'input connections'
area of mythtv-setup.


Also, upgrading to myth(buntu) .21 made my firewire experience a
thousand times more enjoyable.

I run trunk already so my experiences are with trunk. The issue is, I
don't know which channels are unavailable and which ones are -- that's
why I need a scanner - to channel by channel and check.

This isn't a great solution, but it will allow you to determine which
channels are output over firewire without reloading the modules
constantly.

So simply start live tv on a channel that works, then manually using a
channel changer script on the command line, cycle through the channels
you're interested in. If you land on one that doesn't work, use the script
to jump back to the working channel within 5 or 10 seconds and you won't
kill firewire. As I said this isn't a great solution, but I have so few HD
channels that it's easy enough.

a stand-alone firewire CCI/EMI channel scanner is in development and
an alpha version for motorola stbs is now available for testing.

for more information, refer to the "scanfw" thread in this list or the
wiki page for the scanner:
