no signal on hd channels with hauppauge 4000

#1
hi, new problem with new card :( i have given up with the twinhan ad-sp400 picked all channels but hd was intermittent, so ive purchased a hauppauge 4000, installed latest drivers, new install of vista x64 service pack 1,

i have tried all new versions of progdvb with new transponders lists, and in diseqc settings sky 28.2 only, no posistioner etc.. it will scan all channels except s2 hd channels, when i goto transponder scan and select a s2 hd frequency and DVB-S2 box ticked press LOCK the signal is full but no quality and when i press scan nothing

when i select a non hd transponder and click LOCK there is signal and quality, again i have tried with 2 satellite dish inputs signal good

any ideas please
