Is all shows on dishnetwork now broadcast in mp4 format? How about SD channels?
A quick Google search says, "No".I would like to burn something in 1080i from my Dish DVR to a dvd-r in mp4 format on my PS3/ BR player, can this be done?
No. There are at least 10-12 million MPEG-2 only receivers still out there.
I don't know of anything other than HD and a few LiLs that are in MPEG-4.
I don't think you're going to get past the encryption.
