Ok after i did some digging here is a way you can force a burn speed in IMGBurn (or any other burning program), its not really forcing a burn speed it is patching your firmware with a burnspeed you watch to acheive for the media.
1. Open Latest version of mediacodespeededit (1.2.0.10).
2. Load the Max Burner firmware or other firmware you wish to patch
3. In the list find the correct media id of the disk you want to change burn speed for and double click it.
4. Now in the pop up list choose a write strategy that closely matches your media and also has the write speed you want to try... For example replace 8x richoh with 2.4x richoh).
Wait for the list to update, you should now see the write speed you desired alongside the disk id you want to burn. Click save, the file will automatically name itself xxxx.speedpatched.bin.
5. Fire up codeguys flasher util and choose your liteon drive - I check the update boot code box (this may not be needed).
6. Click on write and navigate to your patched firmware, ignore all warnings and let it write.
7. On completion of flash press exit and TURN OFF computer.
8. Wait at least 5 seconds then restart computer, your media should now work at the speed you requested.
Thanks for advice LightningUK it lead me to this workaround once i knew what to look for !!
I have tested this myself and it does work.
