The film festival venue that I’m screening at won’t accept anything less than Blu Ray, so even though it was shot on DV tape, transferred to DVD, I had to dig up the old .mov master and convert it by Friday.
Looks like .264 files were the reason the discs were freezing every few seconds. Don’t know if that’s a compatibility issue with this burner and the Blu Ray player I was testing with, but using .m2v files finally solved it, all the discs I’m making now play beautifully. Thank you Lynda.com for the helpful tips!
