Hi there,
An official Firmware upgrade mostly improve or fix only Basic functionality of the Operating System Kernel. Twonky is a 3rd Party Software. 3rd Party Software only will be upgraded, if this is absolutely necessary for the kernel function - so nearly never!
If you have a Gen2 device (something like DL2100, EX2100, DL4100, EX4100) with Firmware 2.xx.xx, look at this post:
Using this guide you will be able to generate your own custom Firmware with your preferred twonky Version inside.
Changeing / adding autostart sequences or CRON Jobs inside of the Firmware kernel is not really recommended for People without really good Linux experience and knowledge of Linux os start behavior. Only a Little mistake can make your NAS useless!
Best regards and good luck…
