[mythtvnz] Hello and a transcoding problem.

[banksie at khantazi.org]

Just wanted to say hello to the list, I am a Wellington based linux  
newbie and I've recently set up on old machine as an Ubuntu 8.04 based  
mythtv box. It is an AMD Athlon XP 3000+, socket 754, with 2Gb of RAM  
and a Nova T 500 HD as the DVB-T TV reception card.

I've got most of the system running but I do have one curl I am at a  
loss to figure out right now. Because my box isn't the most CPU  
endowed of machines I am taking to transcoding the received programs  
using mythtranscode into an RTjpeg format. This chews disc space  
naturally enough but drops the playback requirements into something my  
machine can handle. (It can do TVNZ 6, 7 and C4 live but anything else  
and it runs out of juice.)

By doing this I can watch TV1 and TV2 programming quite nicely and I  
have been very happy with the quality of picture I am getting. (This  
is being output to a 16:9 SD TV so I am easily pleased on the picture  
quality front.) But I can't do this with TV3 output. The files  
transcode happily enough but while the video is fine the sound output  
is wrong - it is acting like the sound has been speed shifted to about  
half speed so that everyone is talking very deeply and slowly - not at  
all suitable to watch. Does anyone have any practical suggestions for  
how to diagnose/fix this issue? I am open to using a different  
transcoding tool if someone can give me a few pointers as to how to  
integrate it into mythtv...
