Yes I used the channel editor to add the transponders to the reciever. I have not used it to add the program or channel. It shows the same as onscreen of the reciever as far as the options you can enter goes. I looked and it doesnt have any option for MPEG4 to select, but it does have an area to select for encryption.
It has
PMT PID
PCR PID
VIDEO PID
AUDIO PID
TELETEXT PID
AC3 button
Subt button
Scrambled button
New button
For the comment about them scrambling it, he said it is going to be somtime next year and dont purchase the access card at this time. I thought this was the problem it was scrambled until I talked with him. I have been trying to buy the card from them for 4 months so dont worry for now.
