Hi all,

I have some problems with the timeshift function.

When I pause live tv for a few minutes and start it again, after a short period i get Continuity counter errors. This result in short hanging/interference on the screen for maybe 1 or 2 seconds and then continues again for a short time until it occurs again. I need to stop live tv and start again to solve this.
Live tv is setup to use unlimited time and mb and the on demand function is also disabled.

I Tested this with the latest stable and unstable version but with both I experience the same behavior.
Client version is xbmcbuntu 12.2 and raspbmc 12.2

If more info is need, just let me know.

Below you find a part of the logging when problem occurs.

No one have a idea why this is happening?

The size of the internal buffer is 2 * 4096 bytes (the size of two maximum sized sections) by default. The size of this buffer may be changed by using the DMX_SET_BUFFER_SIZE function. If the buffer is not large enough, or if the read operations are not performed fast enough, this may result in a buffer overflow error. In this case EOVERFLOW will be returned, and the circular buffer will be emptied.

Hi shms,

So if I understand you correct I need to change the buffer size to a larger amount? Can you point me a little bit in the good way because google didn't help me that much when looking how to change this value. I found the file and also found the dmx set buffer size, only how i enable it with the correct buffer size? This is what i see in the dmx.h file: #define DMX_SET_BUFFER_SIZE _IO('o', 45)

Thanks
