First ever reply here, hope it's right.....
I think the old Nokia On Digital boxes were built for 2K COFDM systems. As the Digital switchover progresses, I think the transmissions are now in 8K COFDM. I think they also can't cope with the new three-digit channel list -they only went up to Ch99.
Somebody hopefully can elaborate, it's much more technical than that, but my tea's ready!
Don't start me off -I bought an expensive "Digital" TV from a respected manufacturer in 2001 to future proof myself. It's got a 2K tuner, so now has to have a set top box plugged into it!
I found a nice set top box manufactured by "TVonics" a few years ago, about half the size of a Cook's box of matches. It had an RF modulator built in (and no SCART sockets). Sadly, I can't see it on their website anymore.
