Anyone using Nero ever had verification errors?

Well I have on occasion had data verification errors when burning data or dvd-video, but only when burning onto DVD (load of mp3’s, 111 out of 1000+ were reported as ‘inaccessable’)

Also had "Unable to mount volume" message on occasion,

But upon looking at the disc’s in explorer or on standalone dvd player the data played fine (mp3’s + dvd-video)

So went of and found a little util called ‘Beyond Compare 2’ this will compare files & folders in a number of ways, used it to check various ‘failed’ disc’s against the stuff on the HD (Binary mode, byte by byte comparison) and surprise surprise every thing was fine !

Anybody else had similar problems or tried any similar compare proggies?

BTW Yes the media is quite cheap but allways works on my standalone's and pc.
