if they title doesn't come up by upc then try by title to see if you can find it. Sometimes the same release has multiple UPC's (if this is the case, you can change the UPC, from the DVD->Change UPC menu option) If you find it that way just verify the information before you contribute under the new UPC.

If you can't find it and need to add it from scratch all you need to do is uncheck the 'Download Profile From Invelos' option on the add dvd screen. you can then enter the new upc and title. you will be prompted if you want to edit the profile now or you can just add it then add the profile information later if you want. Only suggestion is to read through the contribution rules before you contribute anything to make sure it complies with the rules. if you have questions about the rules ask in the contribution rules forum

I think by 'single dvd container version' he just means that its one keep case with the discs in it versus a slip case with 3 keep cases.

for instance look at these titles






the first two come in a normal size keep case, the second two are boxes.
I bought the 4 film favorites version (for space but also because I really and holding off for them to get a directors cut set of 4, or at least a box that has matching packaging with all 4 movies and the directors cuts that are available, which the 4 film favorites actually has those version)
anyway. that set is 2 discs, each are double sided so one movie on each side of the disc.

the 3rd one is 4 snapper cases and the 4th one is 3 keep cases contained in a slip case.

*edit*
and this one

which is 2 discs, one single layer, one dual layer. both single sided. but they are both in one normal size keep case
