R.D.Redemption DLC question..please help! :)

Hi all...

I dont live in the states at the moment.after looking to pre-order a copy of RDR for the ps3 on ebay, i found a copy at a good price with free shipping.The game is an Asian Copy..there for i am worried i will have trouble with the DLC.i singed up for the Japanese PSN store a few months ago just to take a look...and even manged to DL some free backrounds.My question is this... lets say i want to download the DLC for RDR in the future,i log in to the Japenese PSN store,and lets say i manage to find the RDRMultiplayer free DLC the will be coming out,and manage somehow to DL it...will it work with my copy without any problems?will it be in english?will i be able to play online threw my U.S & Uk account?

thanks all..

but if the game itself is in english (as well as there being a choice for other languages) wont the Japenese DLC be Multi language as well?

Just get the game from Game.co.uk or something. Therefore you won't have any problems with the DLC and as soon as the word 'Asian' is mentioned on eBay I get skeptical.
