Hi Yaobing
I tried as much as I could think of including reinstalling the drivers but still no success with getting the audio back in sync. I have the digital reception working well now but it is only 4 channels and a test broadcast but it looks and sounds very good. FYI the Irish frequency table is the same as that for the UK. but the country code is 353. I may reinstall XP next month which may help. Any other suggestions welcome.
Thanks Tangodude
