Sorry to resurrect such an old thread but......
I have just released the first version of my attempt to create a utility that is a spiritual successor to dvd2daph. The utility currently converts the Dragon's Lair HD video footage from the HD PC DVD-ROM release for use in Daphne. I'm looking for feedback and assistance to expand this to include the 5.1 remastered audio as well as to support the blu-ray releases of Dragon's Lair II and Space Ace.
Please check out my thread for this at
