Nero 7 & DVD buring help please

hello, for some odd reason when I use nero express to burn my dvd files, it now says something about the file being larger than 2gb and for fit of the ISO file system, change to UDF in the compilation. This happened out of know where one day, before that it worked fine. Can anybody tell me how to get it back to usual. Thanks in advance.

Also, i just bought some new dvd-r’s and they dont seem to burn correctly. When i use convert x to dvd, it burns something on the disc but will not work on anything. The computer recognizes it as a blank disc. PLEASE HELP.

Choose UDF/ISO and buy better media.

There is much cheap dvd media on the market…
