Hi,
I tried ivtv v0.4.0 and v0.4.1 both have the distortion under mplayer.
This morning I dropped back to ivtv V0.3.8 and the firmware from the atrpms
kits.
md5sum /lib/modules/HcwMakoA.ROM /lib/modules/ivtv-fw-enc.bin
aa4d1e3dd17667957d8fe5b8d2d19395 /lib/modules/HcwMakoA.ROM
6e2012d919fa48811c27e25e54a0a5dc /lib/modules/ivtv-fw-enc.bin
So far no distortion, and its been running all day. And the picture is much
better then 0.4.1, which had a ghost image off to the right. Maybe it could
be adjusted, I did not try since the distortion was still present.
I do not know if this helped the sound failure issue it is much more
intermittant. It will be several weeks till I am sure that issue is gone or
not.
With the latest ivtv-fw-enc.bin firmware file with a md5sum of:
5f5fa240ada73c3565f5f7de4c7b5138
All three ivtv version I tried would lock up the pvr150 v0.3.8, v0.4.0 and
v0.4.1. But only under mythtv, mplayer had no problems at all. A reload of
the older firmware un-locked the pvr-150 so mplayer or mythtv was happy once
more. I do not have a clue why mthtv would have this issue with only a
firmware change. Mythtv mythtv-frontend-0.18.1-115.rhfc4.at
V0.4.1 and 0.4.0 had a distortion issue under mplayer no matter what firmware
file I tried.
The pvr-150 is on a SBE so it took me a while to figure out the distortion was
only on the SBE recordings and even longer to get it through my head that it
was not just a bad cable or noise.
The intermittant garbled sound was the sampling rate set too low 32000 not
48000.
