DDP image from Wave Editor - MD5 checksum does not match
I have been making DDP images in Wave Editor for years (many times) and everything perfect. Yesterday I sent DDP image to the plant and they wrote me MD5 is not equal ... I sent it again - the same. I made the DDP image again anew (exporting cue/wav from Samplitude etc.). Again the problem.
I wonder what this means ... They said it may be just ok (they checked image.dat etc., I sent them cue/wav itself and they said OK, but they need a written consent from me they can produce the CD in spite of MD5 mismatch.
Of course, it may be OK , but does not sound 100% OK. Can it be a problem of Wave Editor or Mac/Windows issue (they have Windows checking software there) or ?
What can be the resulting problem in the following CD pressing ? Can something get wrong ? How can I check this MD5 myself ? I downloaded some Mac MD5 software but it even did not recognised MD5 file from Wave editor as MD5 valid file ... (could not import ...)
I wrote to Wave Editor support and sent them the files, no response for the last two days.
