alienstream v3 helper testing

[Pbox]

Definitely should. It might be an interrupt priority issue, where the
WiFi processing takes priority over the decoding/sound card serving. You
could just for testing, try to convert the file to WAV (AIFF) and see if
the hiccups still happen.

[Waldy]

Peter,

After a while looking at xine-lib & this stiky buffer thing (which I could
see using the xine-ui front end too), I decided to give up fault finding
(was giving me a headache) & re-compile the xine-lib.

This cured this problem & your helper works now on most streams I have
tried.

Thanks for your hints, I'm new to linux & the sb so its been quite a steep
learning curve.

regards

Waldy
