[linux-dvb] TS Stream - null packets generation?

Hi all,

I am now using a STB (under development) which its hardware
configuration is:

SAA7134 + TDA10046A + TD1316

When I capture the TS stream (which is stream out by a DVB-T modulator),
and compare the file with the original one, I found tones of NULL
packets (which its header is 0x47 0x1F, 0xFF 0x10, and remains are 0x00
... Until the end of a TS packets, 188bytes).

The captured TS is corrupted in a random level, sometimes seriously,
sometimes a bit.

I found these null packets wasted lots of PCI bandwidth and, may these
cause the above error?

And where are the TS null packets come from?

Please help. Thanks.

Best regards,
Lo Chun Chung
