I have some problems with WinDVD 6.
It takes a long time to open and also to close.
When I try to read a DVD on an external HDD via firewire it stops working and I have to restart the computer and can never read this HDD.
Also there are some features of the decoder that sometimes work and others not ( for instance "video effect" ).
Maybe RAM insuficient? I hve P4,2.6Gh,512RAM,AtiRadeon9800pro.
