Hello there I have a Panasonic plasma TV which could play HD videos from a stick. It does not accept the newer h.264 format, however it would accept the divx format in avi container. So I downloaded an xvid encoder, it would show up in the list of codecs in PTE, and I did succesfully produce a 1080p-avi video and show it on the TV (excellent quality). The problem is now - no sound! A web search revealed - the panasonic would accept AC-3 sound, or MPEG-1/Layer-2. I opted for the AC3ACM encoder, installed and registered it, but it does not show up in the list of encoders in PTE. Has anyone a recommendation for me? How does PTE determine the installed audio encoders? How can I check the correct registration of encoders? Any other proposal? Thanks, Mike.
