Have you considered releasing an xvid as a sort of BETA release. I was thinking that once its complete and you do release it there maybe stuff you might have missed which we could help out with spotting before finally releasing a proper DVD version for our DVD shelves ;-)
If you water-marked it somehow to prevent it being a final version and reduced the quality a bit then we could see the work youve done, feedback any comments to you and then if you wanted you could make any changes based on those comments for a version 2.0 release after Xmas.
I guess it would be like a test screening for a movie and we could help with any issues or glitches you might have missed (not saying there will be any of course!!! sometimes when youve been working on something for so long you can miss something without realising...well thats my experience anyway!!)
Just a thought! Personally I dont mind waiting till the middle of next year.
Keep up the good work, if what youve done so far is anything to go by I doubt there will be a single mistake anyway!!....
