[mythtvnz] VDPAU AV-Sync Errors

[Tortise]

I'd also be keen to do some tests for you also Jean-Yves, if can get my new 9.04 box complete with NOVA-T 500 and HDR-4000 to scan 
in some (Kaukau) HD channels to test...  9.04 is supposed to support both.
I keep getting "no signal" when scanning, however a HDHomerun proves there is plenty of signal on the cable.   (92-97%).
Possibly a Tuner firmware issue that applies to both?
Trawling the list there are numerous suggestions, e.g. putting
options dvb-usb-dib0700 force_lna_activation=1
into /etc/modprobe.d/options  This does not exist here, so is it relevant?  Is it also relevant where one has excellent signal?  It 
didn't help. Have also tried putting in DVB tuning delays as suggested upto 1000.  How much is needed?
I've even tried a channels.conf, customised to Kaukau.
Perhaps the appended points somewhere?
Kind regards
David
