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.
