I've changed NBLOCKS to work with PAL and changed several includes to work in RC2. The only problem I have now is with playdv from libdv: - when using gtk display it's slow (around 20 fps on 1.2 GHz Athlon) and therefore sound gets distorted - when using SDL sound is OK but video is approx 1.5 faster than it should be - when playing just audio (--disable-video), it's OK. Is that some problem with libdv/playdv or is it something missing in the DV stream? (Some timing info?) Thanks!
