[dvblast-devel] error: couldn't read from DVR device (Value too large for defined data type)

[Kompan Kolia]

Did you add stream other channel from this server?
I have this problem when i stream too much channels. I have network port overflow.
I streamed channels about 100+Mb, but i have only 100Mb link.
After upgrade link to 1000Mb, trouble is gone...
