I have tested Calibre to generate and read RSS type content both from the built in recipes and some custom content ... I love the concept and would use it regularly .... BUT ...
On pretty much every example of generated content, my Sony PRS-505 crashes and resets randomly after reading a few pages of Calibre generated content. The screen just goes blank and the Sony "starting up" screen appears.
This never happens with normal ebook content.
I have tried setting the output format for Calibre to be EPUB and LRF with the same results.
I am using Calibre rev 0.4.103 but this occurred on the previous revision also.
I still use the Sony eBook library to transfer books to the reader but very rarely and never at the same time as running Calibre.
Anything I can try before giving up on Calibre?
