FreeDVB

Dear friends,
I have installed last version (20211122A), and cccam or scam+ only works in the morning (not weekends).

When we arrive about 8 pm, all channels gets to scramble, and only works for 2-3 minutes every 30 min.

Getting informations on others forums, look like and DDoS attack to cccam servers, or that ISPs are blocking de data (at least in Spain).

Look like that "all decoders" are being affected (except I R I S 2100HD, waiting confirmation by others users).

I would like check with and older firmware (20200630), but I can not found it. Some users started to have problems after upgrade to 20200707, or newer.

I found it;

On the morning of February 10, NTV+ made changes to the structure of ECM. Now bytes 4 and 8 DW (response from the server to decode the image) are not the checksum of the previous 3 bytes. This means that to decode channels, client receiver emulators should now ignore the checksum mismatch and should not check and correct (calculate bytes 4 and 8) and replace them with the sum of the first 3 bytes, but instead use the response that came from the server By default, all emulators check the checksum and correct it as "bad". As a result, the channels are not decrypted, except on the following emulator versions, which continue to work without problems: Mgcamd 1.46, Cccam 2.3.9, Wicardd 1.19 (with the addition of an NTV + reader to the section lines: force_crypted_cw = 1), All other older versions of these and other emulators currently work incorrectly for NTV+, i.e. they automatically fix what does not need to be fixed. As a result, there is no image. Users of linux receivers with Enigma2 OS should install one of the 4 listed emulator versions and continue browsing. Users of Chinese receivers on which it is not possible to install the correct emulator should contact their firmware writers and ask them to fix the problem.
