Hmm, my RPi doesn't boot anymore after updating, no rainbow splash, nothing.
The SD looks OK checking it on my PC but I'll try copying the bootcode.bin, fixup.dat and start.elf from 3rdparty/bootloader in the update archive, SYSTEM from target and KERNEL renamed to kernel.img from target in case one of the files got corrupted, as I am overclocking.
EDIT: Yep, that fixed it so I guess it must have gotten corrupted.
OK, so testing I managed to get it to lock up with a sound looping when stopping TV (and I remembered to switch debug logging on this time) so maybe this will show something useful, or maybe it's just my overclock isn't stable. top currently shows tvheadend using 18-20% and xbmc 9-10% but the log hasn't changed since 17:48 (a few minutes ago). I'll decrease my core_freq from 450 to 333 as I've got a vague feeling I had less problems either with just arm_freq=1000 or maybe also with core_freq=333 but if I still have these problems, I'll disable the core overclock completely and see how it goes with just the arm overclock.

As for the amplification/gain control, I found 30db is about right to get TV, stereo video files and multi-channel movie files around the same volume (this is with the main volume at -10db to leave some room for increasing it for individual files, although it might be better to set it to 0db and use the TV remote to adjust the volume). I think with 20db amplification, TV and stereo video files were OK but movies were a bit quiet still. However, when starting TV there's a loud sound at the start before it settles down, so I guess the automatic gain has nothing to go on at this point and defaults to max 30db before analysing the content and realising it needs to reduce it, so maybe a 1-2s window could be added before the gain becomes active, so that it won't do this? This doesn't happen when switching channels, only when first starting TV.
The Boost Centre Channel when Downmixing option isn't working as it should for me unfortunately and actually seems to make the dialogue quieter when activated. It may be that it's decreasing the L and R channels to boost the Centre channel and a lot of the dialogue might be coming from L or R rather than Centre, such as when the speaker is off to the side of the main character or there's a back and forth conversation between two characters, so unless there's a way to leave the L and R volumes as they are whilst boosting the Centre channel for the dialogue that does come from there (which might be the most important dialogue but we still need to be able to hear what the other characters are saying), I don't think it's going to work. I've only tested with one film (The Hobbit) so far but if that doesn't have all the dialogue on the Center then it's reasonable to assume that other major films won't either.
I'm still seeing the Boost Volume on Downmix in the video files pop-up/blade menu with it showing as disabled, despite it being enabled in System. It might be this menu entry doesn't do anything but it still shouldn't be there. I think this is just a matter of skins needing updating though, as it affects xTV-SAF and Confluence Modified but not Confluence, which shows the Update Library option instead (which the other skins are missing).
