Feel free to place your script on the wiki, at
http://www.mythtv.org/wiki/Category:Firewire_Priming_Scripts
or
http://www.mythtv.org/wiki/Category:Channel_Change_Scripts
and it may make sense to link those category pages from the Firewire
page linked above (but I'll leave that to someone who has actually read
the Firewire page).
Oh, and if anyone would like to lead a project for maintaining (and even
creating new) channel change scripts/programs and firewire priming
scripts/programs, please let me know, and I'll help you get it started.
Having a real repository of code where people who actually use the
scripts/programs could be given commit access would be much better than
having random pages on the wiki, with less-than-ideal versioning and such.
