I bought a Samsung 16X DVD Writer last month.. but its giving a lot of hassles. Out of 8 DVDs I have burnt, 5 have failed, 1 wrote successfully but I am unable to read the contents, 2 are working properly. I wanted to know if it has something to do with the size of files (since I generally write movies > 1 GB). Also does it have to do with the burning speed? For Dual layer, it was mentioned at 2.4X, would it matter if I wrote DVD-R at 2.4X? Another doubt is I am not able to write completely on the disc. If I try to write two files (size 2.5GB and 2 GB) on a 4.7 GB disc, it gives the message, not enough disc space, change the disc. Is anybody else facing the same issues? Thanks.
