[mythtv-users] DVB Tuning issues with 0.20

Having updated to 0.20 from 0.19 I can no longer tune a number of dvb-t 
channels (anything on multiplex A in the uk) using a nova-t USB 2 
(DiBcom 3000P/M-C DVB-T) using kernel 2.6.12-2.3.legacy_FC3.

If I schedule a  recording of any channel on multiplex A it produces a 
zero byte file or if tuning to one of these channels in liveTV the first 
second or so of the channel is recorded and displayed. I have checked 
the dtv_multiplex tables is correct for this multiplex and 0.19 used to 
be able to tune the channels and I can still tune to these channels 
using tzap.

Whilst I realise from from ticket 1502 
http://cvs.mythtv.org/trac/ticket/1502 that this is probably a dvb 
driver issue for this card the patch which closes this ticket implies 
the user definable timeouts and autodetection of this card should work 
around this problem and for the majority of channels this does work.

Does anyone know if changing changing any of the timeout values for this 
DVB card can help here? - I have tried randomly increasing all three 
values with no success and wonder if this is really a tuning timeout 
problem as I do not see any timeout messages in the mythbackend log.

Any help would be greatly appreciated as I am reluctant to regress to 0.19!
