I'm assuming 14 March still produces "bitstream corrupt" on banner.jpg?

Yes, 15 March also.

debug.log (pastebin) for 15 March build when opening "Choose art" dialog for "Arrow" TV Show.

The three images shown in the "Choose art" are (from the top to the bottom, in case the order bears any relation to sequences shown in the debug log): Banner, Poster then Fanart

The 15 March build has firmware dated 4 March.

Code:

rpi512:~ # vcgencmd version
Mar  4 2013 00:06:09
Copyright (c) 2012 Broadcom
version 374181 (release)

There are firmware changes to jpeg decode on 18 March, and 29 March.
It would be interesting if "start.elf" is significant in causing/fixing the hang. Double check that latest firmware doesn't fix it (not sure if you already have that).

My latest git build of OE (finished building just 10 minutes ago) has the following firmware:

Code:

rpi512:~ # uname -a
Linux rpi512 3.6.11 #1 PREEMPT Mon Apr 1 13:10:44 BST 2013 armv6l GNU/Linux
rpi512:~ # vcgencmd version
Mar 19 2013 00:02:38
Copyright (c) 2012 Broadcom
version 377915 (release)

I've rebuilt OE with debug enabled, but gdb doesn't produce anything useful:

Code:
