Re: [Zapping-misc] Parse raw vbi data

[anshul <ans...@gm...>]

*I solved it*, It was an error on my part, I destroyed rd after 
receiving slice for first time.
but then I realized while debugging that Rd should be destroyed only 
when you are done decoding.
and rd has very no relation to each slice.
