The problem is I do not have terrestrial service to test it .... DVB and iptv (streaming) no problem with recording with one or two channels ..
But as I remembered I told you before you have hard ware issue (Your hdd format) ..
So Please forget your hdd now and try with USB drive (format it by pc not dreambox by any program with Linux extension (Ext4)).
Then try to test record two channels ... After that you will get the correct feedbak
