So I’ve had my MythTV humming along real well for the last 2+ months now. Dual PVR-150s, 1/2 Gig of RAM with a meager 60Gig HDD. It has really passed the wife test with flying colors. I have the audio folders remote CIFS (samba) mounted from my NAS box back in the office. I can stream audio files all day long with no problem, but when it came to video I just didn’t have the bandwidth (it seems) to get anywhere. Mplayer was studdering trying to play back the video file. I tried tweaking my WRT54Gs that help the network together, but I my WiFi signal was already around 80-90%. No help there. I dig around on the Knoppmyth wiki until I found an article about switching over to Xine (in this case for DVD iso - pretty slick if you ask me) I swicthed the default video commandline option to:
<code>
xine -pfhq –no-splash %s
</code>

For some reason xine does a better job of buffering the video signal across as slower network mounted drive. Props to Xine on MythTV
