Okay - I'm pulling hair out now.
Got two installations running (Vista on disk1, XP Pro on disk2). BDA drivers downloaded from links earlier in this topic. All mobo drivers are the latest available (Asus P5E-VM HDMI, 4Gb, E8400, TwinHan Cab.CI)
XP Pro - TwinHan software installed - but only picks up a couple of channels.
MediaPortal installed (1.0.2)- no signal!
Vista - TwinHan software installed - pick up loads of channels - freezes when analysing 539000. No sound when viewing FTA - picture is fine (guessing compatibility issues)
Media Portal installed (1.0.2)- no signal!
ProgDVB - no signal!
I've been switching drivers between BDA (1238) and standard installed with TwinhanDTV.
On both installations MP is detecting the card, and setting priority as 2 with the name DTV-DVBC 878 Digital Tuner Filter (Enabled, init etc).
I know that I can pick up transponders on 131000,6952,64-QAM (tested on TwinHanDTV and dbox).
Any pointers on what I could be doing wrong with the BDA driver?
