Wierd...
Could you please provide a sniff (PCAP format) of the problem (off-list, of
course)? It would be very helpful.
Just an educated guess, but I believe Netvision might have an Akamai
node hosted there while 012 may not. Since Youtube uses Akamai as a
CDN, the connection via Netvision only foes through the local loop,
while in other ISPs it does the long haul.
Again, just guessing, but easy to find out - go to an you tube video on
Netvision and 012, get the URL and resolve it through the respective
companies connections (so that GeoIP will give you the right Akamai
node) and trace route to that node from each ISP.
The netvision trip should be very short to their data center while the
012 is probably long haul aboard or goes through the IIX (less likely).
Again, just guessing.
