Got it. Have you already informed Zenitram about the 0.7.59-60 bug?
About FFMS2, AVStoDVD is still equipped with 2.12 release, I did not have the time to check the next releases compatibility. BTW the only flags used are 'track', 'cachefile' and 'seekmode' together with FFVideoSource and FFAudioSource. If nothing has changed about that, you can safely go with 2.17. Let me know.
Bye
