Sonic,
If you're gonna look into changing the source to fix this, I have an additional request. About a year and a half ago there was a thread on standardizing alternate functions (i.e., RRNEXT and RRPREV have multiple functions based on what screen you're currently viewing). I thought we also discussed multifunction labels, but RDS hadn't been implemented at the time. Since its now in RR:

How hard would it be to have RR automatically change ARTIST and ALBUM labels to show RDSNAME and RDSTEXT, respectively, whenever an RDS radio is active? This would be most beneficial when listening to the radio and viewing main.skin in most skins. I currently use switchlabel (ARTIST>>RDSNAME) manually,but could easily be automated using variables, but why put the onus on skinners to accommodate this enhancement, especially since the current source leaves the last played MP3 data in those fields when the radio is active which really looks dumb.



EDIT: Just thought about this again, add the following to your exectbl.ini:
"RADIO", "LOAD;RADIO_PLAYER.SKIN;RADIO||RRNEXT||RRPREV"

This adds a second or two to the radio startup but is a simple solution to the last channel played issue.
