I think I was on 2.1.7 a few days ago and aac and aac+ was streaming fine.

Now on 2.1.8 the streams become stuttery after one minute of playing. Also the buffer time is really long (40 secs) on aac streams on 2.1.8, but is much quicker (3 secs on previous versions).

The stream I used is http://www.bbc.co.uk/radio/listen/live/r3_aaclca.pls .

I had to go back to an earlier version. I have purchased XiiaLive. But the only older versions are copies on file sharing sites. Is there any way I can downgrade my XiiaLive?
