When I playback an ogg file in Rhythmbox, sometimes the playback stops for about 100-300 ms. It is actually audible and very annoying. It happens in FIXED places, in all ogg files I have (I mean: for exapmple in file a.ogg it always happens at 00:04 and 00:07, but in file b.ogg at 00:06 and 00:09 sec), but the time between those short pauses is different everywhere and varies from about 2.5 sec to about 4 sec (and it is very annoying because of this high frequency). However, in some parts of most tracks the pauses does not happen at all, even for some longer time (or I cannot hear them). This is present in rhythmbox only, the same file played, for example, through mplayer, sounds perfect. I checked several audio formats for the same bug, but it seems it is present only when playing ogg files.
I report this bug against gstreamer, because as far as I know it is responsible for audio playback in rhythmbox, but if I'm wrong, please correct me.

I can confirm. This I have observed on Ubuntu 10.10 and Fedora 13.
However, ogg files encoded at 192kps show little or no choppiness whereas those encoded at 160kps are noticeably choppy.
