umm..sorry, its got me beat, most devices I know have SP/LP in the set up menu under options or something, if it isnt on the menus then try holding down input select, if that fails then is there a flap on the VCR facia?, normaly you have the option on the remote or in the menu, failing that it might be on the VCR it`self, failing THAT I am gonna have to think on it, dig out my older recorder manuals etc, that doesn`t have many options for a modern VCR tbh, I like my remotes with lotsa buttons.
[edit] after looking at the sony web site, the player should go to lp/sp automaticaly on playback, and you should have an option in the timer menu to set the recording to sp/lp, you might like to check if your timer menu has that option in it, you could also mail sony support with the model number and ask them, the worst they could do is not reply.
ps whats that button under the one touch record button for, or is that the record button?, on all the Sony remotes I looked at the sp/lp was right next to that Oo button, maybe they kept the same functionality onto this remote.
if there is one thing I can NOT tolerate, it`s intolerant people.
