OGG transcoding and content-length

Hi,
I've setup transcoding for Ogg and have a problem with the estimated content-length calculated by Subsonic.
Sometimes it's accurate but most times it's over by about 15%, which causes my client to think there's more data to come. Even the Apple URL methods downloading the data time-out because they also think there's more data to come, when actually Subsonic has finished.
Is there any way to improve this?
Thanks
Rich
