Re: Still jerky video.. Tips needed..

Hi Todd,

And the story continues..

- Closed Captioning is turned off, both on the PC and the MCX..
- I monitored the network performance tab in Task Manager while the extender
is playing live TV.. (not making use of the network performance tuner) I did
this again yesterday : network load is about 10%, according to task manager.

My colleague has not provided a TV-recording to me just yet.. I punished him
for this, and he promised to give me a recording tomorrow..:-)
