Just some more tips- You'll notice the 3 lines are added above channel names, so like if you find 10510 you can just paste your new 3 lines over the the top of the 3 lines shown above 10510.
Also openDBEdit wasnt editing correctly due to auto-changing the last line, but with that solution above it should now be fine. I have read others have used Editpad, DCC, EnigmaEdit, etc etc so i dont think any other editors have a problem.
scratch that got it sorted
transfered the lamedb file with yummy ftp and opened it with textedit and copied the 3 lines over 10510 transfered back and then unpluged box then powered back on works great thanks
