MP3 to WAV errors

I am trying to convert a demuxed MP3 file to a WAV, the MP3 plays for 1:54 but the converted WAV only plays for 1:47 and the audio is out of sync. Details of the MP3 file - 0x0055(MP3) ID'd as MPEG-1 Layer 3, 128 kb/s (64/ch x 2 ch) CBR, 44100Hz. I have tried conversion with Razorlame, Musicmatch Jukebox and Virtualdub/Vdubmod but all give a different file length for the WAV? I have been looking for something to repair MP3 files as mp3test.exe reports: Testing C:\DVD\1.mp3... First frame invalid Resync: 58 Bytes at 0 (0%) 128kbit, 44100hz, Joint Stereo, Crc: No Resync: 417 Bytes at 2948248 (2%) Resync: 417 Bytes at 6810085 (6%) Resync: 2502 Bytes at 10359172 (10%) Resync: 2919 Bytes at 22407136 (-20%) Resync: 5421 Bytes at 25417459 (-17%) Resync: 2502 Bytes at 28510348 (-14%) Resync: 5421 Bytes at 34088557 (-8%) Resync: 3336 Bytes at 57086941 (14%) Resync: 2919 Bytes at 58685302 (15%) Resync: 3753 Bytes at 60837856 (17%) Resync: 1668 Bytes at 60899989 (18%) Resync: 3336 Bytes at 67918516 (-18%) Resync: 1251 Bytes at 69649900 (-16%) Resync: 1251 Bytes at 73229011 (-12%) Resync: 6672 Bytes at 75306922 (-10%) Resync: 2919 Bytes at 84325798 (-1%) Resync: 2502 Bytes at 89626285 (3%) Resync: 7089 Bytes at 99448303 (13%) Frames: 238490 Errors: 19 (0.06%) -- NOT OK -- Done. But I dont seem to be able to get the file repaired? I tried running AC3 fix on it int he hope it may work but it did not :( Thanks for your help in advance.

you can repair it with BeSplit/BeSliced.

Thanks, I have tried Besplit but I have found that it simply deletes the bad parts in a file and not replace them with blanks so the file is shorter and the audio is still out of sync? When I have problems with AC3 files I use AC3FIX which does keeps the file's length correct?? Thanks
