DNLA is a very dubious "standard", and can mean practically whatever the 
manufacturer wants it to mean. There is no assurance that one DNLA-compliant 
device will work with any other specific DNLA-compliant device.

Well, knowing the exact encoding needed would be a *very* good start. 

get_iplayer's .mp4 videos are h264 video & ACC audio. Your blu-ray player 
should be able to cope with that, because blu-rays also carry video with these 
encodings.

The PS3 is made by the same manufacturer as your player, was released 5 years 
ago, and has no problem playing get_iplayer .mp4 videos.

You can stream to the PS3 using DNLA and the MediaTomb server, but I do now 
recall mention that Sony's implementation of DNLA there is horrendous.

I have streamed get_iplayer's MP4 videos to the PS3 this way.

If you can put a video on a memory stick or SDcard, or burn it to a CD / DVD 
and play it on your player, then the exact same video should work fine over 
DNLA.

TL;DR: I'd make sure first that this isn't a problem with DNLA, rather than the 
video format.

If you do indeed need to mess with the video encoding, then use `get_iplayer 
--raw` and the ffmpeg documentation [1] [2] [3]. Ask any questions on the 
ffmpeg mailing list or elsewhere until you've got a file format you can play / 
stream to your Sony. Further questions are probably not relevant to this 
mailing list, or to get_iplayer, until you have converted the BBC's .flv file 
(that you get using "--raw") into a format you can play - only then we can tell 
you about get_iplayer integration.
