Hi,

I have a TT C1500 card (saa7146, STV0297) which had problems tuning
channels at QAM128 (like the ones in the Finnish HTV / Welho network).

A fix which seems to work perfectly so far is to change the delay for
QAM128 to the same values as for QAM256 in stv0297_set_frontend(),
stv0297.c (line ~395, kernel 2.6.15):

case QAM_128:
	delay = 200;
	sweeprate = 500;
	break;

Anyone who can view QAM64 channels but isn't able to tune in to QAM128
might want to give this a try.

Regards,
