Help with converting BBC HD Stream to DVD (Normal methods won't work)

[Killer3737]

Hi Guys,

I hope i'm posting this in the correct place, seems the most relevant.

Firstly i'll just say i have no problem converting 99% of Transport Streams to SD-DVD. I know of all the required programs and settings, so i'm not new when it comes to this.

However, i have just grabbed off Usenet a TS which was recorded from the BBC (UK) HD stream.

It is a H.264 1080i stream, in a TS container. Now i have had a good look on google and found several programs/solutions on how to encode these streams. However, after several hours and program upon program, i cannot get anything to work. Here is what i have managed -

- demuxed to .mpv and .ac3 files.

Now this worked eventually using a program called xport, but from here is where my problems start.

I cannot find a MPEG-2 Encoder that will load this file, let alone re-encode it.

Cinema Craft Encoder SP2 either doesn't load it at all, or if i load it with a AviSynth Script it crashes. The same goes for any other program. They crash (stop responding) when i try to add the file.

I have had both the CoreAVC codec and ffdshow codec installed, and it hasn't worked with either.

From further research i have also found that the BBC HD stream uses MBAFF Interlacing, which is maybe causing a problem?


My PC:
XP SP 2
Intel Celeron D 2.8 Ghz
1.18GB Ram
Not sure on Video card, but it's one that came in my PC, bought 1 1/2 years ago.

So does anyone know of a way to do this?

Thanks

The mpv extension may confuse your software, as most will assume this to be an mpeg-2 elementary stream, when it is not. Try opening your avisynth script in virtualdub to see if there is an indication as to why it is crashing.

Thanks, i'm at work now but i'll give it a try when i get home.

But as an alternative, do you know if it is possible to demux to a file with different extension using xport, or any other program?

All our digital broadcasts are mpeg-2, so I only know the theory, but not had the opportunity to do it practically. There are a few interesting looking tools in the Muxer/Demuxer section - take a look there.
