A quick note:
AVCHD folders/support and management is ready. All compatible AVCHD folders are listed at the top of the list with different color and with [Video] prefix.
I extended the array for title properties with few new fields:
char content; //type of title: PS2 | PS3 | AVCHD
char details; //load AVCHD details from details.txt
Each AVCHD video title will display the contents of details.txt if present.
Here is how it looks. If AVCHD folder contains multiple titles (like those compilations produced by other tool multiAVCHD), the first is displayed in the title name and the rest are displayed with smaller font below the title.
