TV card causes 100% CPU usage on 3 channels

[speeddad]

After a few months of toying with my TVcard, I got it to work in linux, with Kaffeine. After about a month of working, I started having this problem. This started about a month ago. My vague guess is that during a normal upgrade, a component upgrade started the problem.

My issue is that 3 atsc channels are "choppy". The video skips and is not smooth. The more movement on the screen the "choppier" it gets. All the other channels are fine.

According to KDE System Guard, when the video for these 3 channels is being displayed, CPU usage is 100%. When viewing these 3 channels, XORG system percentage is over 60%, but on other channels it veries from 1% to 6%. When these 3 channels are on in the background, but not being displayed, CPU usage is normal and XORG percentage is under 5%.





This is a copy of channels.dvb (I added the '**' to show which channels have the problem. TV|WHA HD does have the problem, but wpt2 and wpt3 do not.)

Updates:

The problem is the same.

I upgraded my kernel, just got the latest Xorg update.

I did find out how to check my Xorg version (Xorg -version) and I got the following message.

It is not supported in any way.

I assume this is the standard version for Xorg.

I fixed it.

On a friend's advise, I played with the videodriver. Under settings-xine Engine Parameters-Video, I changed the driver from auto to xshm. At least that is the one that worked for me.
