I still wait for a firmware that accept 16 Gb or 32 Gb USB keys to timeshift. Generaly you record on other equipment than TV, but timeshift would be usefull and i don't want to buy a 250 Gb drive with external power supply only to timeshift on my 32PFL4007. You just have to put the limit on 10 Gb or to only write something and let it go if lower than limit.
