WD TV Live Streaming no MP4 video

Hi I have a problem with playing some MP4 files on my WD TV live streaming. I have searched for similar issues in the past and have downgraded the firmware to 2.01.86. Also try using the mkvtoolnix to change the container to mkv. but the new file in Mkv doesn’t even play saying unsupported format while when it was in original .mp4 the file is playing only the sound with no video showing at all.
Below is the media information for the original mp4 file. Thanks in advanced for any advice.

Not Supported by WD TV players

Hi Joey, Thanks for your reply. I looked at the link you gave me. It seems that there is no information on how to reencode the media with bit depth 10 to bit depth 8. The information I found by googling is how to convert L5.1 to L4.1. can you suggest me a program or guide on how to reencode the media to 8 bit ?

Thanks

almost 100% sure any video encoder out there, by default, will encode to 8 Bit

anyways, the most popular [free] encoder that people use is Handbrake

Hi Joey, Thanks a lot for the suggestion. Tried handbreak and it worked like a charm. Thanks again.
