[mythtv] Nuppelvideo format question

[Alex]

Hey, I've already written a couple of times regarding a windows frontend
that I'm writing. I'm having trouble getting the nuppelvideo files to
convert using the patched version of mplayer (using mencoder +
mythencoder.pl). When I convert I only get 3 frames, always!

I also couldn't get windows media player or bsplayer to
play the nuv files (wmp shows the music graphic and _tries_ to play the
audio, whereas bs player says unknown format). I've installed the nuv
directshow filters for windows and fdshow. The dshow filters property
pages give the right info.

If anyone can help with the above problem, that'd be great. I've searched
the forums but wasn't able to find anything.

Regarding the nuv format:

I'm just constantly polling the backend with
'REQUEST_BLOCK_RINGBUF[]:[]128000' and saving the data I get to a file. Am
I doing this correctly? I noticed that 'mythtv' gets two 128000 segments
and then seeks back to the beginning... is this for the 2 second buffer?
Also, is there anything else I need to save to the nuv file after I'm all
done (like a closing header or something)?

I hope to get live tv with pause/ff/rw on windows. I've
got the code down but I can't get through this (these) problem(s).

Anyways, any help is appreciated.
Thanks!
