Most strange. v3.7 for T816 makes sense though, in the sense that my T816 box is running v3.4 (not freeview playback compliant - i.e. no accurate recording, unlike the v1.0 twin record software for the T810). Perhaps Vestel are testing the auto update feature of the T816 box to make sure it works, since all the updates I've applied in the past have been via serial cable. Or maybe it is an error on the DTG page.
AFAIK there is no single record software for T816 boxes, so the question is where can T816 boxes be found in retail??? I'd certainly recommend them over the T810. T816 boxes don't necessarily look any different to T810 boxes, btw - but the sticker on the underside should indicate what type it is
This may indicate, as I mentioned in another thread, that Argos will be stocking T816 Digihomes in their new catalogue, hence why they've reduced the prices for their end of catalogue sale (all 3 Argos branches here are out of stock of both the PVR80 and PVR160). IIRC, it's a year ago since the Digihome (T810) first appeared at Argos.
