Hi Trial,
my idea can it not be.
I have now activate tuner B- init 4- set /proc/stb/vmpeg/0/xres to "0"- init 3. Box start again with tuner A and it come no crash.
But what i noticed, first read from directory /proc/ over ftp takes some time.(1-2 sec) Can it be a timeout issue when ServiceInfo will read from /proc/stb/vmpeg/0/xres?
