unexpected stop -> service crashed

HEllo,

version 2.1.7 stopped always working after 50 minutes. First hickup came after 40minutes. Version 2.1.9 is better it can run longer.  But sometimes the core crashes when i tap on the widget, and sometimes it stop playing (2.1.7 stopped the time counter, but still displayed playing) with the message "unexpected stop". When I tap 2-3 times on Stop the message "service crashed" ist display (instead of "playing", lower right edge). Then I can tap on play again and it continues working.

I have a chineese android pad. If you want to  I can mail screenshots from systeminfo. I'm using WLAN and MPEG streams.

Regards, Mo
