Nero Recode 2 encounters an error and closes when using some wmv files


I have been trying to recode a number of movies using recode 2. I am converting them from mainly wmv files to mpeg4 and with the majority of them there is no problem. Every now and then I come upon a file which you can’t import and it causes nero to close down giving the error report “Nero Recode 2 has encountered an error and needs to close” It is always the same files that it does this with but there seems to be nothing to indicate a problem with the file.

Any advice from anybody would be greatly received.

Oh one other thing the files that cause the error work fine in Nero Show Time 3.
