stv0298 signal issues on QAM256



Hi.

Unfortunatly my cable provider "Comhem" moved almost all channels to QAM256.
The results are terrible on my two cards. Blocky picture and skipping audio.
I've tried all suggestions i've found on mailing lists to change different values in stv0297.c but without luck. What i cannot see is, if those who reported problems since 2005, are happy now or not. Perhaps this hardware is too obsolete.
On other devices QAM256 is ok.
Anyway im hoping for some help or some information to make me decide about placing these card in the junkbox.
