if what the OP said 2 posts ago is correct, then it is not due to DRM removal, as he said he checked the post-DRM mobi fiels & they were still OK

Note that I have not seen this behaviour ever, & I've converted many retail .mobi ( not topaz) books to epub.

if you could reproduce this error with a book from amazon's bestselling free books, & post just the book title, other could download a free legal copy & test to see if they get the same conversion error.

why not post the titles of the books were you have the most annoyances, someone else may own the same book & be able to check.

you could also try converting mobi to rtf, or to txt, IF as you claim the .mobi file in calibre is OK, then you may be able to narrow down wwhere the problem is occuring.

STEP BY STEP - to trace exactly where errorsa are being introduced, you need to compare
1. retail mobi ( with drm ) read in Kindle for PC,
2. the de-drmed Mobi, after importing to calibre, but also read with kindle for PC. ( use open path, then open file within calibre database
3. same file as 2 but read with calibre viewer ( which causes an internal conversion to epub)
4. same file converted to other checkable formats - txt, rtf....

it could also be to do with specific versions of plug-ins and of kindle for PC. I followed advice elsewhere had have not allowed Kindle for PC to update beyond v1.4, as plug ins were reported to have issues with v1.5 & higher. but if your books are OK at step 2 above, then it is NOT due to DRM removal.

PS I'm not sure whether a .mobi extension is a reliable way to detect topaz. I think not ,& I think you have to examine file headers via notepad++. I was given that advice in another thread.

posting book titles shoulod not break any board rules.
