I have same or similar prob with WMP11. Not sure when it first occurred, as I havent tried a burn till today. I have two drives. Tried with both drives and different new discs.
Insert a blank disk and
- Explorer pops up showing disc is recognized.
- WMP switches from 'No Disc' to 'Unknown' over on LHS under Library
- 'Insert a blank CD' (IABCD) stays just above the burn list.
I close the Explorer window just in case. Now I drag some titles over. IABCD is replaced momentarily by 'Calculating...' and then back to IABCD.
I then click on 'Start Burn' The CD tray opens, 'Insert Media' message box appears ...
now I am in a loop.
- If I click on Cancel, WMP just goes back to square one (flashes up Burn Complete, despite tray being open) then goes inactive and waiting for user interaction.
- If instead I push the disc back in, Explorer comes up showing the disc and WMP remains with the Insert Media message box (until I click cancel again, when 'Burn Complete' shows down in bottom bar).
Just to be clear, no burning happens!
