[mythtv-users] dct6200 firewire problems, choppy video, scrambled sound

[Marc]

Hello Team,

I am running Mythbuntu 8.04, Intel 2.8 single core, 2Gb RAM combo  
frontend/backend.

Until recently, I had two Hauppage150 tuners and live was a breeze.

I got myself a Shaw HDTV receiver (not PVR) - Motorola DCT6200 and was  
hoping to hook it up via Firewire to record HD and SD content.

I did remove one of the Tuners sitting on /dev/video1 and added a new  
Firewire tuner via mythtv-setup. Nothing worked.

I then ran firewire_tester and got if finally to connect on broadcast.  
And here's where the problems started.

1. If I chose to watch live TV via Firewire port, the picture emerges  
and freezes, the sound appears but it is scrambled.
2. If I select to record, the recording starts and I can play the  
recording later, but the recording plays choppy, the playback area is  
640x480 and the sound is scrambled.

Any suggestions as what is going on?

I am using an Asrock Mobo that does not have native 1394, so I have  
plugged in nGear Firewire 1394 PCI Adapter Card 3 Ext 1 INT Ports. I  
did not install any additional drivers for it, it looks like it works  
out of the box.

I also have two different channel lineups configured. The 150 tuner is  
hooked up to schedulesdirect analog channels and firewire to the  
digital lineup, this way I do not have my analog recorder grabbing  
scrambled signal off the higher HD channels.

Cheers,

dscheste

There are a few more important things we need to know.
1. What is the resolution of the video on the channel you are trying to
watch play recorded video from?
2. What video card are you using?
3. Have you checked processor usage during playback?

It sounds like your system can not handle the video source and it has
nothing to do with the firewire an cable box.
