I would be for sure ready to subscribe if the PodCasts give additional contents not available on the LLVJ DVD version (I think about "specials" like equipment field reviews, workshops, interviews...or even some parts of DVD videos which did/would not fit into the DVD version)(*).
Not sure in case the PodCasts would be same content as the DVD version:
I have no iPod and beeing my notebook (MS XP) all I need for info-education-entertainment, I wouldn't see (for me) any advantage apart from a potential ready available backup-archive in case of DVD future wear out...
too much watching and re-watching, you know!
e.g. what about a quick and dirty China trip trailer or, if available, the Brickworks or...?
yes, I know, may be asking too much...
