[linux-dvb] NEWSTRUCT and QAM_XX

["=?ISO-8859-15?Q?Panu=20Kek=E4l=E4inen?=" <dvb@panu.fastmail.fm>]

Hello!

Having problems with Siemens dvb-c card and QAM_128 modulation I tried
the NEWSTRUCT driver.
Every time I try to tune to any other channel bouquet than the one that
uses QAM_64 modulation, the card somehow locks and can't tune even the
QAM_64 bouquet.

channels.conf contains following 2 lines:
TV1:283000000:INVERSION_ON:5900000:FEC_AUTO:QAM_128:512:650
nelonen:162000000:INVERSION_ON:6900000:FEC_AUTO:QAM_64:512:650

After loading the dvb modules tune to "nelonen", then "TV1" which does
not tune, and back to "nelonen" again, and now it doesn't lock either.
I can reproduce this every time after reloading the kernel modules. I
just tested that it doesn't matter if the second channel is defined to
be QAM_128 or QAM_256.
