I am slightly confused by the information you give.
I am wondering if it is possible to bun HD format movies to my bul-Ray drive in HD Format,, I did try but it can't recognize the The blu-Ray drive insted burn it in other format
Which machine is not able to recognize the drive?!?! Your PC? A DM800 does not have any BD-drive built in!
is there any way or any other Immage to do it?
The image does not really care! After recording to the internal HDD you have to copy the stream to you PC, convert it to a BD-structure and burn it to a disc (UDF2.5 as I remember for BD).
