I have had a Series 3 for a long time and live in a rural area that receives weak signals from 4 or 5 different markets. It has accumulated about 265 channels in its memory, and will be gaining more with local frequency reassignment occurring on the 18th. I utilize the "channel strength" utility quite often and many phantom/obsolete channels use the same PSIP assignment, which makes checking channel strength quite annoying. Is there a way to wipe out this channel list and start from scratch? I'm guessing "Clear and delete everything" would accomplish this. If so, Is there a way to go through that process without actually erasing all of my recordings?
