Ok, this is interesting. The PC had been off for a
couple days. After
turning it on I ran firewire_tester succesfully:

[root at magic contrib]# ./firewire_tester -p -n 0 -r
5
Action: Test P2P connection 5 times, node 0, channel 0
P2P: Testing...Success, 226 packets received
P2P: Testing...Success, 631 packets received
P2P: Testing...Success, 258 packets received
P2P: Testing...Success, 257 packets received
P2P: Testing...Success, 259 packets received

I then ran test-mpeg2 > test.mpg and was able to view
the captured mpeg in
mplayer. Everything good, I fired up Myth and tried
watching live tv. Same
result - It would tune to channel 560 and then dump me
back to the myth
interface, same errors as before.

But I decided to test recording for the heck of it. I
went to manage
recordings - scheduled recordings and told it to
record SNL. I let it run
for a few seconds and tried watching the recording -
Blank screen. I
manually changed the channel via the cable box remote,
and surprisingly,
video started to show up. Even more interesting, it
was Cinemax HD. I cycled
through channels via the remote and am able to watch
all the premium
channels, both HD and non HD. The non HD channels have
some tearing with a
Prebuffering Pause error in the terminal, but I'm not
worried about that for
now.

Right now I'm trying to figure out why it won't let me
watch Live TV or
succesfully change channels. Any ideas?

------------------------------


I'm also using Charter and was able to get this
working with alot of tweaking... I used the sa3250ch
as the channel changer which works with the '-s'
option to choose the alternative channel changing
method, otherwise it changes to the wrong channel. So,
make sure you get the sa3250ch.c file from the latest
SVN version, and also check your channel source
settings in myhthtv-setup to make sure the default
channel is set right.

More importantly, I also found that for the last month
Charter had set all the channels to "free" with no 5C
encryption and firewire was working great :). However,
just a few days ago, they switched and are all
encrypted with exception to the few broadcast
(HD)channels (like PBS, NBC, ABC, etc).

Can anyone else here confirm this change by Charter?

I wonder if this was just a 'blip' in their system
where they opened up everything, then realized their
mistake and shut out all the channels from "free"
access.
