If you used "this channel" rules in old versions or you have the "this 
channel" filter enabled with current MythTV and you delete all your 
channels (which you should do with "Delete all video sources" - see 
http://www.gossamer-threads.com/lists/mythtv/users/264034#264034 for 
details) and rescan, the rules will continue to work without issue as 
long as the channel call sign is the same.  The channel number is 
irrelevant.  Note, though, that because the call sign is user-editable 
data, if the scan picks up a different call sign for channels, you can 
always change the call sign back to the old value if you prefer that 
approach over updating the channel on your recording rules (or just 
remove the "this channel" filter from the rules).
