[mythtv-users] Hauppauge 350: "cat /dev/video0 > test.mpg" then how to play back w hardware decode?

[mark a stephens]

Finally got mythtv up and running.  For Live Tv and recording it  
works just swell.  I'm impressed!

This is on an AMD K6 400MHz whopper, with a H-350 card, Linux kernel  
2.6.16, ivtv 0.6, ivtv_xdriver_src_0.10.6.  MythVideo is also  
installed.  The poor PC is headless and connected to a TV.  I use ssh  
and vnc to connect.  This is my first attempt before a possible  
purchase of a mini-ITX system better suited to a living room.

Using MythVideo, I tried playing a DVD ripped avi and the video  
worked (perhaps slow?) but the sound is not there.  This is as  
expected for a slow CPU.  Ok, mplayer is  probably not setup right.   
Found out it may not even be possible to have mplayer use the  
hardware decoding capabilities of the 350.  (and then I found out  
this is being dropped from mythtv,... bummer!)

So I tried boiling it down into a simple problem:
	cat /dev/video0 > test.mpg

followed by:
	mplayer -fs -zoom -vo xv test.mpg

The video is there, but in slow mo and there is no sound.

A
	cat test.mpg > /dev/video16
produces the sound just fine.

Are there any mplayer settings folks have used to get the mpeg2  
decoder of the H-350 to work?  Any other player software?

And if mythtv can do it from the video it captures, is there a way I  
can convert the test.mpg (an possibly those DVD avi files) into that  
format?

I just started playing around with ffmpeg to convert avi's but I  
thought it simpler to do a capture and play routine first.

thanks!
