Steve - spot on - you've covered some ground !

i upgraded the ivtv drivers from 0.4.3 to 0.4.5 to 0.4.6, same problem. I stayed with R5B7.

i found reference to this problem http://ivtvdriver.org/trac/ticket/79 but no follow up - i've
posted to the author...

incidentally, the VIDEO picture is much sharper/smoother/better on .45 & .46, sound is now failing
more often ;) 

the Aerial is good - no probs with sound on my NICAM VCR or with my mono BT878 card, cabling is
short and simple between aerial and PVR. Picture is strong and clear, no static, we also get C4,
Triangle (weakly - no uhf elements), juice, maori (good programming). 

so good people - your opinions poleaze

* return the PVR150 under warrantee - replace it with another version (i'll check their support
for linux)
* Buy new Aerial
* Get a magic signal booster thingy from Dick Smith - Do they work?
* Revert to my mono BT878 and shelve the PVR as a bad investment ??

thanks,Paul.
