I did some testing last night with my MiniBud and this is what I found:
The AZBox Elite wouldn't lock the signal after I added the Frequency 4008H 2480SR not matter if I went up or down from 4007H frequency. I then scanned with the DVB World USB 2104D. It logged the transponder, 4008H 2480SR and and 7/8 FEC, but wouldn't display video. To display video I had to manually edit a channel (video was breaking up very badly and very unstable). I noticed that the quality meter was fluctuating between 0 and 50%.

The Coolsat 5000 had a steady 66% quality, but no video was displayed. I then tested on the Viewsat Ultra, it scanned in at a steady 25% quality, but video was barely displayed and breaking up. I think the reduction or loss of quality signal from that transponder could be because, the FEC has changed from 3/4 to 7/8.
