The "unexpected ECM reply" is indeed gone and things have improved, but it is still not working okay. The signal is being decoded, giving a new still image about every second. I believe this is caused by incorrect ECM messages.

0100&00006A is the correct message, I believe the others are wrong (for example 0000&000100) and are being rejected by oscam correctly.
