[mythtv-users] Doubled screen - Is this any interlace issue?

["José Tomás @ Chico"]

Hi!

The X.Org driver didn't work, the system works fine but when mythtv 
starts the machine freezes the screen, only net access make me able to 
recover.
The filter was success! Using standard filter make me able to see all 
image and touch the other issue I have, that is audio rate sampling is 
not correct.

During this I noticed that since a month ago a new driver update was 
available at ATI, installing was again easy and everything worked 
perfectly after also apply filter.

So the filter is the solution.

Prior this solution I had no sound, now I have but in wrong rate.
Issue which is addressed by google 
query:"site:http://mythtv.org/pipermail/mythtv-users/ audio rate saa7134"

Seems those posts didn't conclude enough a solution, do you have any 
knowledge about how to solve this issue?
I just read the posts today, I didn't have time to test any 
recommendation available there.

Regarding filters, do you know any kind of filter that improves image 
quality?
Improvements like removing snow or rain image low quality effects.

Thanks and regards!
