Right, I also thinks there must be regularity in network corruption rather
than simple randomness, otherwise I would see different effects. What
bothers me even more is how PID-TO-TS bandwidth can influence the
corruption rate (in case it's DMA based but I yet have to investigate it)

Does it have large FIFO and other advantages that are missing in 7146
for good TS input?
