s***, aye, never did respond to the responses. Apologies.
After all that, I decided to pick up another ZV:M 2nd hand. Was on the verge of getting a Cowon S9, but decided against it, partly to save money, partly because I didn't like the fact the memory isn't expandable and partly just because I'm a bit p*ssed off with flash memory. I liked my workhorse.
Don't know how my original got broken but guess it involved getting sandwiched between 12 hardback books in a rucksack. Cracked LCD and seems unwilling to turn on. Annoying as there is some life in it, though.
