I am adding patch for Video_AR fix to SamyGO.py.
Stay tuned for DTS,
If it possible, will be harder than AR_Fix :)

Right now adding DTS is extremely hard if not impossible. I've checked how audio formats are handled. DTS is detected and then definied as unknown audio type and simply handled with the audio stream skipper routines. I've already wrote down in one of the topics the routines, pointer tables are involved.

However I've made my asm, c projects and I'm now able to inject code into the exeDSP that is written in arm assembler or c. If the 8500 or 9000 series will support DTS we can track down how it is done and adding new code written in C is making firmware modding much more easier.

About AR I've made some discoveries and also compiled a new patch. More details about that in the reverse engineering topic.

For me the AR problem is fixed now with my V2 fw mod. Now I'll investigate the audio track thing deeply. In the V2 mod of mine I've already enabled audio stream selection for _all_ kinds of AVI files not just for divx files. (However it has a bug in the firmware -- if the first track is DTS than if you switch to other tracks they wont work :( )

DTS library could be compiled as static library for ARM arthitecture for injection.
The point is not only capturing for DTS initalization, we need also redirect entire DTS stream flow/packets to our code.

I think we can inject DTS code for pass-thru if media type is unavailable.

NewAgeHun, Coudn't you redirect DTS code as a PCM flow? Since TV supports PCM Wave and no one use it in movies, than we could replace PCM / WAV code as DTS Pass-thru mode which don't needed to extract / process DTS stream packets. I don't know if DTS pass-thru is need any initialization for work but I thought that is easier than injecting whole DTS code object. :geek:
