You can buy a clone from a company like Remotes.com. Their prices are surprisingly low on this unit. (Sometimes this is not always so!) You can find it here:

http://remotes.com/remotes/servlet/rs?a=gmi&uuid=12370820789860&smodel=MT2274&brand_pn=MEMOREX_MT2274

If you do not see your exact remote here, chances are, from the codes you listed for your set, you actually have an MT2274A. If so, then try here, instead:

http://remotes.com/remotes/servlet/rs?a=gmi&uuid=12370820789860&smodel=MT2274A&brand_pn=MEMOREX_MT2274A

(If you do have the MT2274 and not the MT2274A, and would prefer an original remote, I, personally, have one I would be glad to sell you. Just let me know.)

Hope this helps in some small way!
