Problem with high bit-rate m4a files

I am having problems with high bitrate m4a files in Opensuse 11.0 x64. Basically, for audio files that have a 192 bitrate, the sound is very choppy. Lower bitrate files work fine.

I have a fast system, so there should be no problem there, and they worked up until recently. The problem is the same regardless of the media player I use.

I’m not sure if there has been an update to the codecs that has caused it, or maybe to the xine plugin.

Anybody else experiencing a similar problem or can recommend a solution?
