Audio Video sync problem

#1
After few seconds I start watching any TV (DVBT) channel, the audio anticipates the video and the lag increases going on. I tried many combinations of audio/video codec configuration. I tried "Use audio processor" option checked and not checked without luck.
Moreover if I use the software WinTV from Hauppauge v4.6b video and audio are synced.

My configuration
ProgDVB for Windows 2000/XP/Vista last version 6.11.8
dvbt card Hauppauge WinTV HVR-900H
MB Asus P6T
CPU i7 920
Video Ati Radeon 4800
Audio Realtek ALC1200

I found an older version (5) and it works ... I hope this bug will be solved in next releases else I will never able to upgrade ProgDVB.
