been using nero for years but i have had enough of the errors and coasters. been using nero 9 but because of errors of the years i don't want to upgrade to 12 but instead find a alternative. paid or not as long as it can do what nero does and gives me 3d smart menus and add audio background etc. i have loads of music videos and over the years have created compilation dvd's but now i want to created compilation blu ray but nero giving me errors. i have burned the created blu ray to a folder, then used imgburn to create a iso instead of wasting blu ray discs as expensive and done it that way. i start the iso and it works up until halfway through the song it starts to slow down and lag. is there any other software that can do what i want? i heard roxio creator nxt is just as bad.

thank you
