What is surprising me is the lack of takeup from any developers on making a DS filter for this format. Nobody appears to be leaping for the spec and trying to make one. I am sure everyone would love an extra 100 megs of available data on their 80 min CD-R's without sacrificing error protection (which should not be an issue with OGM etc). From what I have read it looks like it should be a simple enough task for anyone with DS filter programming knowledge. I may be wrong however as I cannot program to save my life (Well perhaps a little crappy basic)
Those last example files are from Ingo. Where can I find out more on what he is up to?
