I am testing it with the tuner input (I am in a PAL/50Hz country) and notice that either the tuner has a poor sensitivity (but the audio comes out with very good qualyty -- I know it is less critical...) or the Bt848 is a bit critical in locking into the sync, unless the signal is very strong. In the meteor driver there were parameters (different for 50 and 60Hz) to locate precisely the position of sync pulses . Is there anything similar for the Bt848 ? Can someone send me a copy of the relevant info so that I can try to patch the driver ?
