I have checked. Before the patch:
Manual scan 12174L/DVB-S/4340/ 3/4 found channel TVN, and it worked.
Manual scan 12284R/DVB-S/27500/ 3/4, after the scan switch to channel TVN, it has wrong transponder data, and it is not working.
After the patch, everything is working properly. After 12284R scan TVN data does not change and it worked.
Please add a patch to fix this problem.
