dug out this old fta dvb receiver dmt 2000 astro tel I did a factory reset clear all the satellites/transponders in memory ,when I go into edit transpnders on renaming the satellites to new satellites names like amc 15 etc ,etc, and you put in the freq and sr numbers and save to the list it won"t save it and the screen freezes having to unplug re start over again to store the info on selecting new satellites from the old lists am I only limited to a select few transponders ? or do I have to use the old satellite names and sub for the new satellite to make things work right ? any old astrotel dmt 2000 users out there ? I haven"t upgraded to an s2 receiver yet as I am limited to an old primestar dish in my apt for the ku bands
