hi,
I tried your patch with TT dvb-c 2.1 premium and the latest firmware 2623
kernel 2.6.13 and almost the latest dvb/v4l drivers
my cable-provider is iesy (hessen)
frq = 121mhz qam256
for NTV and some of the other private-channels
the patch has no effect I've still several drop-outs
if I watch a channel with qam256 modulation

maybe I can support you with some debug output
just tell me which data is important to improve the qam256 support in ves1820

maybe youve got a old wallplug with ~120MHz trap...
the qam256 problem is mainly frequency independend.


patch contains correction for viterbi monitor flag, wrong SYNC register bit
used before in ves1820.c(?).
cant use hg head - doesnt build dvb-ttpci.ko dont know why, yet.
