Hi,
I have narrowed down the problem to the changes from MythTv
CVS 2004-11-29 to 2004-11-30.
I have further narrowed this down to the file:
libs/libmyth/audiooutputoss.cpp, Line: 112
"soundcard_buffer_size = info.bytes;"
This line was added in 2004-11-30. On my system this sets
soundcard_buffer_size from 0 to 65536.
If I remove this line the "juddering" goes away ....
Note that my system is currenly using the OSS driver, although
I had the same problem with the ALSA driver.
