Welcome to RockBox
I think it's best you read the manual. Really.
What you're seeing is the file browser which is where you end up when you boot
To record, open the menu by pressing the A-B button. There you can select recording.
Be sure to set the recording settings first (source, encoding,...).
Take some time to play around with it before actually taping a concert.
It boots up with the bootloader then it for 1/2 a second I think i see "rockbox" pop up then it goes to a screen with the batt meter... something like a volume meter...a square box..then a "return" arrow
then it has a "folder" with RECORD beside it and
then what looks like an x with rockbox written beside it
This is the filebrowser. The top line you see is the statusbar
when I choose record it then gives 2 options audio / voice...but nothing comes up
You've just entered the 'record' subdirectory and you see two more subdirectories. This whole 'record' subdir tree is created by the official iriver firmware. If it's empty you can remove it (highlight the 'record' dir and long-press the joystick, select delete subdir)
when I choose rockbox it shoots to that quick glimpse of "rockbox" then returns to the above.
Congratulations on using RoLo, the RockBox loader. That 'rockbox.iriver' file is in fact the rockbox program, by selecting it you executed it which means you restarted RockBox.
