Hehe no problem, twas my fault, reading my post again I could see it was ambiguous hehe.
From a thread on here I know the release notes for 4.18 are...
- Correction to support for PL button on CR-415 remote control.
- Minor corrections to bass management for MLP.
- Pro Logic Auto setting now works correctly with HDCD discs.
- Front panel navigation menu item added.
- Separate audio delay settings for PAL and NTSC now replace the original Audio delay menu item of the Audio page.
- Player responds more quickly to the command to come out of stand-by.
- Removal of screen corruption when switching between Setup menu and Programme menu.
- Fixed Programme menu for DVDs.
- Skip-back for DVDs now works as for CDs (skips to beginning of current chapter / track, not to the beginning of the previous chapter / track.
- Problem of screen going blank in interlaced mode when switching between PAL / NTSC is fixed.
- Support for DV78 RS232 control.
...but I was really after like a revision history, i.e. what's changes/improvements have there been in the releases since v3.00 (the one I have). Is that what you have or does it just cover the 4.18 improvements?
