Hi,
Test is being taken by random selection of channel, not the channel you want to test. You may take tests even every day, and each time, test channel will be different. This is general test. If you want to test any particular channel, you may ask about the channel on the forum.
Also, you may take a 3-day test of any particular package (it is paid).
All data received in the billing are added to newcamd.list file, not cable.xml.
Please read the forum, all mgcamd settings are described.
