Thomson DTI 6300-16 - Top Up TV Anytime

I have had one of these for six months, they are nothing but trouble. The software is unstable which causes the unit to frequently freeze. To reset it requires switching the power off and back on at the plug; sometimes more than once. When it isn't frozen, it will randomly decide to either not record at all, or only record a few minutes of a programme. The amount of displayed recording time left, never equates; you can have 58 hours recording time left, record an hour long programme and find after it has recorded you then only have say 25 hours left!
Most other reviewers of this unit that I have seen elsewhere all say don't buy one, spend a little extra and purchase something that actually is 'fit for the purpose intended.
