Well, first of all I want to say that the whole ISO download idea is great. It took me about 5 hours to download the Solo Blues 1 ISO and the DVD worked great (I burned with a MAC freeware program called Burn). The only problem I'm having is that the PDF tab files are not working. The message says they are damaged. Anybody had this problem? Any solutions? Thanks
Your Mac should have a utility called 'md5sum'. You can use this to check that your PDFs are undamaged by comparing the MD5 hash of your files to that of a known-good version of the same file.
You tell md5sum to calculate MD5 hashes of your files by opening a terminal and typing something like this:
(Your DVD probably isn't mounted as /media/cdrom, though -- go with what ever is appropriate. You may even be able to drag and drop the files into the terminal from Finder)
Assuming the ISOs you download are exactly the same as those used to master the physical dvd I bought a few months ago, your md5sums should be:
f8f50eaae1b909e490f4432931c6eb69 /media/cdrom/SB1-1-Walkin Easy Blues.pdf
a7563dea6360420cb83d1dee61199efa /media/cdrom/SB1-2-Steady Thumb Blues.pdf
1e512e1794f99c7381663d27145ec25d /media/cdrom/SB1-3-Gospel Blues.pdf
(Again, the file names will probably be slightly different for you on account of me not using a Mac)
If those all check out (each file should produce the same number), then your PDFs are fine and the reader is (probably) misbehaving.
If the numbers are different, then it's possible that the PDFs have been regenerated between my DVD being mastered and the ISO you bought being produced, or it could be that something went wrong with your download and the PDFs really are busted.
