I had this problem recently too, I have 3 PVR150 cards each fed from a
DirecTV reciever. MythTV works great using the perl script to change
each recievers channel, but it won't initially tune channel 3 on any of
the cards. After a reboot I manually have to use ptune to change the
channel on the cards (just once per reboot, but it's still a pain). Do
you happen to be using a cable box/other reciever to feed your PVR350?<br>

<p><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;">Hi,</span></font></p>
<p><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;"> </span></font></p>
<p><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;">I have recently updated my mythtv build from a CVS version
of early June this year to the latest svn version (7270). My PVR-350 is now not
tuning properly, all the channels show snow. Looking at the backend log and the
kernel debug for the ivtv driver, everything appears to be happening as
expected. The v4l ioctl is called and the i2c command issued.</span></font></p>
<p><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;"> </span></font></p>
<p><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;">Maybe there has been a change in the card initialisation.</span></font></p>
<p><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;"> </span></font></p>
<p><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;">What have I missed?</span></font></p>
<p><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;"> </span></font></p>
<p><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;">I have looked back through the list archives and cannot see
this problem mentioned.</span></font></p>
<p><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;"> </span></font></p>
<p><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;">I have not rerun mythsetup, do I need to do this?</span></font></p>
<p><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;"> </span></font></p>
<p><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;">Reverting to the old version, without changing any config,
makes the problem disappear.</span></font></p>
<p><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;"> </span></font></p>
<p><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;">Any help gratefully received. So I can get on to looking at
the other problems I have noticed (increased CPU load, slight jerkiness in
playback, hangs when switching DVB channels :-( )</span></font></p>
