Hi meinert,
in you last logs there is something totally wrong. TVE3 fails in of the first steps when building the graph. Perhaps an other application was using the card when you tried TVE3 this time.
Unfortunately the error occurs before TVE3 looks for the software encoders. It failed also in the last log before adding the encoders. If I look at the definition in CaptureCardDefinitions.xml than I see that this card is using your sound card as audio capture. Your first log confirms this assumption:
2008-02-07 17:20:43.421875 [4]: analog: failed to find audio/video pins
Such cards are currently not supported by TVE3.
The problem is that I'm not quite sure, if it's a good idea to use the sound card in TVE3, because it could have some side effects in other applications.
meinert,
Have you installed all patches from windows update(might not help your card but should get rid off those errors)?
Been browsing around & it seems like your 100e it's a hardware card & not software......
