Those buffer warnings are normal and can be ignored. They are just from
blocks using vector sizes that are not a power of 2.
The input file (adv16.cfile) is not a Transport Stream, it's an IQ file
of a DVB-T transmission. The flow graph stops after a while because the
"repeat" parameter on the file source is set to "No".
The IQ file is provided to test the flow graph. The next step would be
to disable the file source and throttle block and enable the UHD USRP
source block (or some other source block for your specific SDR) and try
to receive a signal over the air.
And as Marcus said, this is really a GNU Radio question.

Hi, I am running “dvbt_rx_8k.grc” with sample ts file. The result save
to the output file and also with UDP sink I can see the video stream
in the vlc. But every time it stop after a while and generated output
ts file with fixed size of 25.2MB. here is the warning I receive gnu
radio:

If this isn't OK, consider padding your structure to a power-of-two
bytes. On this platform, our allocation granularity is 4096 bytes.
