Help! errors in CAPTURED UDP stream that I know is perfectly clean of errors

Hi Wiresharkers, I'm a newbie so please pardon me if I describe my problem clumsily. Attached is a picture of the way I capture a file. I do the next: 1. I inject a perfectly clean MPEG stream over UDP into a PC with Ethernet 1Gigabit interface network card. (I know it's clean for sure, and anyway I also checked by some reliable testing tools such as StreamXpert running on the same PC, connected to the same interface port) 2. I close all windows, no program is running on the PC. The UDP stream continues flowing in all the time. 3. I open Wireshark, set a capture-file and start recording (I tried with and without filtering only the relevant IP). 4. From the resulting capture-file I'm striping the MPEG stream out of the UDP encapsulation. (did this a hundred times, it's 100% reliable) 5. in the resulting MPEG stream I get "Continuity-Counter Errors" which means packets were lost or mixed with another stream. 6. Actually, instead of steps 4-5 I later on simply ran Wireshark's MPEG-TS-checker and indeed the Wireshark itself reported the same CC Errors! Have you ever encountered such a problem? Could it be that Wireshark is too weak to record a ~50Mbps stream into a capture file? What should I do?? Thanks in advance, Roni
