I use version 306 on a Vu+ Duo with Blackhole. I have never had the problem of it defaulting to internal flash and only once has it not updated the EPG itself, even a manual download would not update the data. I discovered the crossepg.descriptors.db file had grown to a huge 60+MB. I deleted that file (actually all the contents of the /media/*/crossepg folder) and it started to update properly again.
So it may be worth keeping an eye on the size of the db files in the /crossepg/ folder and flush them occasionally.
I do reboot the box with cron daily just before doing the CrossEPG timer update and run the lsk free memory plugin to try and minimize any problems.
