<div dir="ltr"> Thanks .. thats where I started :-) Had the analog cards in and as soon as I added the DVB-S cards the problem erupted. Attacked it from the othe end (i.e. DVB-S and then analog) and still come with the same problem.<br>

<br>
I had a play with xawtv and couldn't get much further ahead. I then
checked dmesg and saw that ivtv0 was being loaded up with the wrong
PAL standard (not B/G). I then used v4l2ctl to set the PAL format, and
tuning frequency for each of video0 (PVR350) and video1 (PVR250).<br>
<br>
I then just tried cat /dev/video0 >test.mpg for each of the
PVR350/250. The PVR350 still gave an empty file but the PVR250 pulled
down a nice file :-)<br>
<br>
So at least I am getting somewhere :-) The PVR350 is one of those
super multi standard ones (it does PAL, SECAM and NTSC on the one card)
whereas the PVR250 is just a straight PAL B/G. <br>
<br>
Anyhow, I rebooted the machine and checked the standard on the PVR350
and it said it was PAL (funny I thought it would default back to the
multi standard .. funnily dmesg says it is PAL-I and vl2ctl says it is
all PAL standards). So I tried a capture again on this card (after
setting the frequency) and it came up with a capture that was crappy
quality, so it looks to still be capturing in PAL-I.<br>
<br>
So in summary it looks like the multi standard card is causing me
grief. Anybody got any experience in setting standards via MythTV or
ivtv with these multi standard cards (I thought all of this had been fixed up in ivtv .. in earlier years I had
to set all kinds of settings in the card at boot up)?<br><br> Worst case is I install the other PAL B/G 350 I
have and run with the PAL B/G 250 as well.<br>
<br>
Thanks again Steve, your back to basics approach looks to have solved
the problem (I was naively thinking that if I was getting the card
tuned in then clearly it had a signal etc so must be some other issue).<br>
