I don't know if the V6 box is better but iPlayer on the V4 is horrendously slow (in fact all the Beeb stuff is...)Two Samsungs and an older LG in the house, all pretty good though the best is the most recent, a 2 yr old Samsung HD ready Smart TV.
I prefer buying something cheaply just after production's discontinued, rather than paying more for one just before it's discontinued. The turnover in models is such that you're unlikely to find the exact model anyone else recommends still on sale.
Was glad to get a Smart TV at the time; not sure I'd bother now. If you have Virgin, they offer iPlayer and Youtube on the Tivo box, and for anything else I plug an HDMI lead into the laptop. This does mean building new furniture to support the laptop close enough to the telly.
No problems at all on my V6. Are we talking about the same thing? There's a connection between the router and the V6 box, so it's the full internet version of iPlayer. I didn't realise you could do this on the V4 box. I thought V4 delivered catch-up through the digital TV service, which is a bit clunky.I don't know if the V6 box is better but iPlayer on the V4 is horrendously slow (in fact all the Beeb stuff is...)
