i 've patched pat.c and now remux.c
and with use xine-lib-1.2 with your second patch (who has typo error)
and that doesn't work.

corrected remux.c

line 533
case SI::AC3DescriptorTag:
+case SI::EnhancedAC3DescriptorTag:


and in line 191:

-Target[i++] = SI::AC3DescriptorTag;
+Target[i++] = SI::EnhancedAC3DescriptorTag;



with your previously patch and just pat.c patched with
line 402

case SI::AC3DescriptorTag:
+case SI:EnhancedAC3DescriptorTag:

that worked but not stable.

Is your sample eac3 has |"Spectral extension" ?
because in france dvb-t with eac3 has it
and need a ffmpeg patched for that.
And i test with that sound.
