Ordered a digihome dtr80 from e-bay.They sent me a pvr 80 with 5.3 firmware.Phoned them up and I am getting hassle from them as they said pvr80 at the top but gave the dtr picture and link of the dtr80 on argos.I tried the machine and for the first few minutes it works okay then it breaks up all the time.Anyone have any ideas how to fix it because I may be stuck with it.It was a present for my sister.Do not know anything about these pvr,s as I have two digifusions.Any help much appreciated.
