Im not sure how good it is but in Argos theres a Digihome set top box for only
£ 19.99
It has digital text, (DVB) subtitles, auto setup, remote control, 7 day EPG.
I'd recommend investing in a DTT-PVR if you have the money, their well worth the money and you can upgrade the HDDs for next to nothing these days, HDDs keep coming down in price monthly ish.
Best investment i made in an electrical product.: laalaa :
