The broadcast was really noisy, the cable seems less noisy.  So I don't
think this would be it.

In general I want to blame this problem on the computer and maybe upgrade,
It does exhibit odd behavior such as taking 10 minutes to start up (hangs at
first bios screen), and Windows refused to install on it a while back, just

But it still strikes me as odd that it was working ok on broadcast.

But if it worked before it should work now. I would first make sure

I tried cutting max and regular bit rates in half.  I forget the values.
And that didn't help.  I also tried increasing the resolution and that
didn't help, I'm not sure why it would help but this MythDora FAQ says to do
that (http://g-ding.tv/?q=FAQ)

I'm not sure about this.

Since you're running Mythdora you might post the problem on their

I'll give that a try too.

Thanks again for the help,
