Hi Chris,

Thanks for this - I was in the middle of trying to sort this out when it arrived! When I use it with dvbscan, however, it seems to mis-detect the modulation on the SDN multiplex. It's telling me it's QPSK rather than QAM_64. Did you have any trouble with re-tuning?

WARNING: filter timeout pid 0x0011

Many thanks

Ian

I had problems with MythTV (.23-fixes) which failed to detect any channels on this multiplex. Had to manually add it with the correct info before doing another scan. Using dvbsnoop to dump the NIT also shows QPSK instead of QAM_64.
