i tried the AEI digisender plug and go from argos using the same box as yours and i'm afriad it didn't work..picture broke up occasionally,but most annoying thing was a continual hissing sound coming through on the audio..apparently after i did a bit of searching on google,its the Scientific Atlanta box that theres a problem with and some pace boxes..also i found out that cordless dect phones and wireless routers and believe it or not,energy saving light bulbs affect digisenders quite bad..also after further research if you get [see link below]should be alright..although i've not treid it yet as they're not in stock at the moment..
i hasten to add that this is only my opinion,as i know others who have got normal digisenders and they work fine,so i guess its a case of try it and see..get one from argos or that one from maplin and if dont work at least you can just take it back mate..
