lchiu7: Hi WayneAll my recordings from DVB-T play fine on the PCH, but with no audio. I've never had to transcode any files to get them to play. I cant remember the firmware version number off the top of my head but I'm using the latest firmware (that you currently get when you choose to update your firmware from the settings screen). It also worked with previous releases of the firmware for me.
I shouldn't have used the full terms! What I did was transcode the video to .m2ts format using Tsremuxer. That creates a file that the PCH can play albeit with no audio.
Are you saying you can play the files with no transcoding but with no audio? What firmware are you using?
I did try dynamically converting the audio to AC3 at recording time, and it kind of worked, but unfortunately I couldnt get the combination of directshow filters to produce a file that played smoothly. They always ended up with some timing issues (5 seconds smooth with perfect audio followed by 5 seconds stuttering, smooth, stuttering ... etc).
Syabas are looking at the AAC-HE LATM format but the problem is the Sigma chipset used doesn't natively support this format so they have to write code to do it. That's not eactly on their high priority list given it's just for NZ and Norway!I dont think its the chipset, but rather some software modules in the SDK that is responsible for decoding AAC etc. A week or so ago they told to me by email that the new Sigma SDK does have some ACC LATM support but they havnt got it working yet. In post on their forums a couple of days ago they indicated the same thing http://www.networkedmediatank.com/viewtopic.php?t=2647 (see the bit mentioning AAC HE).
If people continue to post about it on the NMT forums, then the issue is likely to get more attention, which equals quicker fix for us...
