I have a mini dvd video camera. Are the mini dvds ok to insert into my MacBook? I tried putting it into the slot and usually it will grab the disk and suck it in, but it did not do that this time. I do not know if this was because I was not pushing it in hard enough or if MacBooks can not use those types of disks. I do not want to push it in and have it get stuck!! Please let me know if it is ok to put them into my laptop! Thanks!!!
