There is known problem leaving the menu guide that
causes this problem. There is currently no known
workaround though i have had some ideas recently but
havent had time to investigate them. Since this now
happens for me regularly i may take a look at this
over the next few weeks.

Feed the output of the 350 to the line in of your
sound card and make sure the line in volume is turned
off and that it isn't muted.

Yes. The Programe guide problem is caused because this
uses X to then access the frame buffer and the code
switches alpha around to make this happen and timeing
issues cause it to go wrong sometimes.
