WEEEeeelll...
I have several Asian horror bootlegs myself, they are copies of either the Hong Kong releases or occasionally British ones that never made it over here. But in those cases the "original" non-bootleg ones were in the system already and I used those for my collection. If you have rips of say HK releases, try to find the info for the real HK DVDs somewhere online (like Amazon) and enter that in. Now, I have one DVD that I think was made from Japanese VHS, I don't think the series ever went to DVD, so I'm not going to enter that one. They do ask for UPC codes on the Enter form, which you probably won't have for a bootleg (mine don't have them). Like I said I didn't have to enter those but I did want to enter in #5 of a series of volumes for which I do have 1-4, so my entry for #5 didn't include the UPC. The request hasn't been processed yet so I don't know if it will be accepted or not.
