Decompressing a split RAR archive

I have a mpeg file which is compressed and split into 11 volumes in a RAR format. As usual for the program - the first volume in the sequence has a normal .rar file extension with subsequent volume extensions enumerated as .r00, .r01, r02 etc. How do I decompress and unite the volumes? When I open each volume I can see the mpg file its total size and the size of the individual volume. When I try to extract a the first single volume (JL.rar) I see the progress box as it decompresses but when it reaches the end I get the following message in a WinRar warning box: Message # 1. CRC failed in JL.mpg. File is broken. When I do the same with any of the other volumes the same thing happens and I get the following messages: Message # 1. CRC failed in JL.mpg. File is broken. Message # 2 JL.r01: Unexpected end of archive. How do I decompress and unite the file's components so I can view the file? Thanks in advance.

Do you have WinRAR installed? The latest version - 5 has changes that are not compatible with older versions. So if it was created with 5, and you have 4, it will not unrar. If you have WinRAR installed & integrated into the right click menu, select the first file .rar, right click and select extract here. If it still errors it is junk.
