I actually have a recording of the ABC airing of Coby. The quality is about a 6/10. If anything the mexican tape could provide a nice clean audio track for Coby! I am still keeping my eyes open for it too.
I am still gathering all of my sources together to see if I can produce a quality set. Not giving up yet!
FYI, I think that I have moved on from using the UK tapes as the video master. There is some terrible frame blending going on with the horrible NTSC-> PAL conversion. Although the audio tracks are the best out there for english. And it is one of the only versions of The Great Heap on tape.
The Japanese tapes have proven to be much better video masters. It is very easy to perform an IVTC on them resulting in blend-free progressive video. The only problem being that the video and UK audio don't always match up (commercial breaks and what not) so you have to keep going in and cutting up the audio track all over the place.
I am thinking about getting together what I have and releasing an MKV/MP4 set just to get something out there. Not sure if I have the energy for a DVD set as this project has already taken me almost 2 years. I am beginning to understand why so many people have attempted to make a Droids set and quit before releasing anything :(
