This is only from memory, no link or direct reference. I remember reading the Telechips 8902 has an issue with Dolby and HD audio. No issues with the video encoding. But something about audio rendering. You may have a compatibility issue of the audio. That is why it may or may not work on some TVs. The HDMI for some TVs render the sound data differently. This could be a mish-mash. But it would make sense.
