BTV 3.7.2 doen't work with plextor!!

[emaayan]

hi... i've just installed BTV 3.7.2 my current system also has a pvr2000 card.

i told BTV to auto scan channels with plextor TV402U but when it comes to previewing it says "failed to build tv graph.

if i use winDVR i can see the programs which means the plextor is working.

also another question.

if i don't configure the pvr2000 in BTV will i still miss the divx recording feature?

i've read that if the system has 2 cards and one does not support divx recordings BTV will remove that completly (don't know why though).
