Title: CPU usage in Media Jukebox TV and Hauppauge WDM driver
Post by: Yaobing on February 27, 2002, 08:21:21 am

To those whose CPU usage goes up too high while running MJ TV:

This probably pertains to Hauppauge WinTV with WDM driver only. I have implemented a work-around of this problem. Until I have found a better solution, please try the following:

Select "Options"->"Video Preview Pin..." on context menu. Choose a different format from the "Color Space / Compression" combo box - YUY2 and YV12 work best for me, you can experiment to find one that gives you lowest CPU usage. The new format will be remembered and used when you restart TV.

For some reason which I have not figured out, RGB555 and RGB24 formats consume way too much CPU.

Hope this works for you.

I forgot to mention that the work-around is in build 8.0.214

Yaobing,
I just started using 2.0.215. I can no longer start the TV. I get a white screen with "ATL 3.0: MJTVCtrl" written in the center. I tried changing some of the options, but that didn't seem to help. Any ideas? Thanks.

Ubae,

Did you start in S-Video channel instead of a numerical channel? If that is the case, try clicking a numerical channel, then go back to S-Video. This is a bug that I will try to fix asap.

Yaobing,
That did the trick. Thanks for your help.
