Cant find more channels (DVB-C)

#1
hi, my problem with the newer progdvb version is:
i can only find channels with 256qam! every other transponder with 64qam isnt working :/.

i could scan fine on the older version (like 4.85 or 5.0x).

im using a TT premium C-2300 (SS1).

any ideas? when i use my old channel list i can watch the channels which couldnt be scanned :/.
