Freeze every two minutes

[somebodyx]

Hi, I have a vlm server on windows xp. It plays IPTV programs. It uses udp streaming. The playback on windows 7 client is perfect. But when I try to play it on the same computer only in linux, the stream freezes every two minutes(accurate to the second). Freeze lasts only 2 seconds, but then the picture and sound aren't in sync anymore. I use opensuse 12.1 linux and have port 1234 opened in firewall.
Any suggestions?
Thanks

Solved it by setting BSSID of my access point in the KDE NetworkManager profile.
