Just want to provide an update after some usage as I've noticed a few issues.
With BerryBoot, RasPlex is slightly slower in UI response. Not by much and still quite usable, but you can feel it if you go back to a raw rasplex setup.
There's also occasional stability issues. Sometimes when trying to play a movie, it would either reboot, or goes to a blank screen (which you can exit via ESC). Rebooting seems to make it better, but not consistently. It also seems to get stuck occasionally if I fast forward or backward. I tried restore the image (a nice BerryBoot feature), it didn't really help.
This is with a newer 16G card that I purchased for pi2. Speedtest indicate it's about the same as my older amazon card (~18mb/s).
I've gone back to a regular clean rasplex setup with the old amazon card and that seems to work fine with all the files I throw at it. I'll test this again when the 0.6.x version comes out and hope it works better.
@agentplex007: You are quite correct in your evaluation of operation under BerryBoot being slightly slower than for a standalone RasPlex image.
This is due to two inevitable factors affecting all images installed for BerryBoot. One is the fact that all access to the RasPlex filesystem is done through the virtual SquashFS-based filesystem implemented by BerryBoot. Another is the fact that all kernel routines are accessed by linkage to the ones supplied by BerryBoot. These two factors are at the same time both strengths and weaknesses of the BerryBoot method.
Strength, because these methods are what allows multiple OS to be used on the same SD card this way. Weakness, because these methods inevitably slow down some responses and place limits on kernel improvements.
As for problems with FastForward and ReWind operations in RasPlex playback, these are well-known issues not unique to BerryBoot usage. All existing RasPlex releases have some issues with those operations, though the precise symptoms may vary. Current beta tests indicate significant improvements in this functionality for the next public release.
