I have a similar setup, despite what Sony's faq says the PS3 doesn't  
like playing ac3 in a ps programme stream file, it has to be in a  
transport stream, maybe this is your problem, where do your AVC/AC3  
files come from? I record transport streams from DVBS and DVBT Freesat  
& Freeview in the UK I also find that the PS3 is not happy if the  
broadcaster messes up the stream labelling, BBC HD currently labels  
AC3 as mpeg2 audio, the PS3 ignores the AC3 audio and plays the audio  
description mpeg2 instead. I get the odd recording from Boston MA too  
and I find some channels are shown as corrupted by the PS3 on either  
streaming server. I find tsMuxeR to be a partial solution, it produces  
files that stream and play but audio sync is variable and the PS3  
stops playing if you try to seek faster than 1.5x or backwards at all.

I find that with some files when MythTV streams them the PS3 will not  
play but when streamed by MediaTomb they stream fine! I haven't worked  
out exactly what's going on but mime types seem very important to the  
PS3.

I have a few scripts that fix up BBC HD and ITV HD such that the PS3  
can play them but not working 100% yet.

I wish I could find a meaningful feedback route to SCEE as I'm sure  
the issues are pretty minor if fixed in the PS3 but cause a big pain  
to fix with free scriptable linux software.

You could try running one of the files through TSDoctor, it's very  
good at fixing up transport streams misconfigured by broadcasters! It  
works well enough under Wine if you don't have any Windows but it's  
purely gui so not much use for a proper fix.
