Maybe it would be a good idea to tell us which version (MKV or AVCHD) and how (using which software) are you burning, since this is indeed a unique issue - I even played the MKV on my Samsung standalone from an external HDD and had no such problem. And the AVCHD version or the MKV simply remuxed to m2ts should play in a PS3 as well. Also did you try playing it in VLC directly from the burned disc?
Not sure if it is mkv or AVC HD
