DSTB (NTL and Sky+) problems are universal. I understand the Pace has 1 processor and the Samsung has 2 processors hence why the Samsung can be more reliable over the Pace.
Having NTL TV and a DVDR is, in a sense PVR already but, obviously using 2 seperate equipments.
However Sky+ DSTB (normal sky with a built in digital video recorder (no VoD)) suffers greatly from all sorts of ailments - it's no more reliable than NTL's DSTB and Sky's doesn't even had VoD.
Imagine using the BBC IMP and SkyByBroadband (Sky's version of VoD) together on your PC. The bandwidth would be through the roof!
You can't turn off Sky's appliaction - even after you un-install it
More hassle than it's worth and a costly one at that
