Synopsis::

installation of MP was not a problem. but after scanning analogue TV channels, I cannot see them (black screen). I've tried several channels, but always the same. in belgium we have the PAL/BG standard, and I've tried PAL/B -/G even'default in edit channel...
what did go wrong ? did I forget something important ?
is there a codec-related problem ?

the tv card is operating well with powercinema...

thanks in advance,
wavemaster

I have a similar probably, but using MSI MEGASKY 580 USB DVB-T tuner. Black box & no audio using MyTV. I've tried all sorts of codec combinations, to no avail, but it plays DVD OK.
Also, I don't appear to have any VMR9 or Overlay options that everyone keeps mentioning. My setup is an Asus A7N8X-E Deluxe with an Athlon XP 2600+, 768MB RAM, 120GB + 40GB HDD, Windows XP Pro SP2, nVidia Geforce FX 5700 Ultra using Forceware v84.21 drivers, DirectX v9.0c and an MSI MEGASKY 580 DVB-T USB TV receiver.
Anyone any ideas?
