My DCT-6200 works pretty well with firewire and I do all that is
mentioned below. However, I do get some of the glitches you talk
about. Mine occur mainly at the very beginning of the recording. It
seems to just skip 5 seconds or so and pick up afterwards.
I also have a weird problem where the node will just switch on me all
of a sudden. It will be going along happily on node 0 and then
recordings will just stop (sometimes right in the middle of a show).
I check plugreport and the node has changed to 1 for no apparent
reason. So, I switch it to 1 in the myth database and go along for a
while and it will change back to 0. I've never seen a node of 2 however.

there was a thread a while back regarding this. You can search on
Gossamer for
more info. basically you want to run this bash script. It will set
the p2p or
broadcast connection to 1 depending on what your machine will use.
From what
I've found bcast is prefered when available, which is why it comes
second
(since its one or the other) p2p is sometimes only available and
when this is
the case its fine. data_rate doesn't need to be 3, but it increases
speed if
your using firewire for capture and not just channel changing. I
have it run
before mythbackend starts when I run it via init.d and I've found
it resets
sometimes so I run it hourly as a cron job.
oh, and the -n # is which node it is. In case you have more than
one firewire
connection have it run for each connection as well.
#!/bin/bash
plugctl -n 2 opcr[0].channel=63
plugctl -n 2 opcr[0].n_p2p_connections=1
plugctl -n 2 opcr[0].bcast_connection=1
plugctl -n 2 opcr[0].data_rate=3

Hi,
My mythtv system is running on an AMD Athlon XP 2400+ (2 GHz)
with 1G
RAM, a PVR-350 and firewire capture from my Motorola DCT-6200 cable
box. Whenever I do firewire capture from the box through Myth, the
recording exhibits a audio/video glitching. The picture will
momentarily become pixelated and there will be a brief skip. I can
tell the glitch is in the recording because when I rewind and
playback
it is reproducible. There is no pattern or regularity to the
glitching. Sometimes it will be at the start of the show and will
disappear in the middle, only to reappear later. It doesn't
prevent
me from recording shows, but is just become a huge annoyance
that I'd
like to take care of. Does anyone have any idea what might be
wrong?
Do you think a faster processor would help?
Thanks in advance,
Azmat
run plugreport and paste the output.
