Thank you again for your hard work. I posted back a while about 1028 or at7500 having issues with a particular signal and posted a file for it. I have narrowed it down to 1 particular type of signal...DVB S2 30000 SR 5/6 FEC...does not matter if channel is MPEG 2 or 4 ... the tuner has trouble locking that signal...S2 8psk 30000 SR 5/6 FEC......thank you for looking at that.
