OK, I bought some Verbatim DL discs. It wrote fine, but it encountered a problem when trying to verify. Log follows: I 20:14:09 ImgBurn Version 2.5.5.0 started!

I've only just encountered this problem, but it has been driving me up the wall (particularly as I've never had a problem burning DL discs using ImgBurn before). I've used the exact same discs before in ImgBurn with no problem (TDK double layer DVD+R), so I'm puzzled as to what the problem might be. Any help would be appreciated. Log is as follows. (It's been the exact same error message every time the problem has occurred.) I 10:51:23 ImgBurn Version 2.5.5.0 started!
