Try to turn off VBI in Myth. I had the similar "echo" problem. Do not forget to reload ivtv drivers

I'm having a problem, and am still trying to narrow it down, but I thought I'd post the symptoms in case this is a know problem.
I'm using a PVR-500 with an AMD64 in 32 bit mode, kernel 2.6.11.7, and MythTV. The PVR-500 is in a master backend, and I am using a separate frontend to watch recordings.
With ivtv-0.3.2y, Myth will happily record programs for weeks on its
own. However, if I watch a prerecorded program on the frontend
(basically just pulling video over NFS), the backend will eventually
(roughly three times per half hour) reboot. There are no error messages
in messages or syslog.
If I move up to ivtv-0.3.4j, I no longer get the reboots. I've recorded
two shows at the same time, while watching a different recorded one
with the frontend at the same time, for over an hour, with no reboots.
However, both live TV, and the recordings made during this time, can
get into a horrible echo state, so bad you can not make out most
dialog. It appears that the video skips a short bit, and then the echo
starts, gets progressively worse, gets progressively better, and then
is gone for a short while. Viewing the recordings on two different
front ends shows that the echo is in the recording. It is not a simple
single echo, like listening to the same audio through two different
outputs where one is delayed, this is like yelling on a canyon, with
roughly four decreasing echos. But with dialog, it sounds like a real
mess.
Wow!
Thanks a million. Not only did that fix the echo problem above, but I have been delaying switching from my old TiVo to Myth because of video stuttering problems with live TV, and those went away as well. And I have spent *way* too much time trying to figure that one out.
