freezing multicast stream

[MarcScherer]

hi,

if i'm playing a multicast stream for 3 or 4 houres the player will begin to slow down unit the video completly stagnate.
Restarting the Stream fixes the Problem for the next 3 houres.
Increasing the cache value in the udp access modul will protracting this.
(500ms ~ 4-5 houres, 800ms ~ 5-6 houres ... )

(sorry for my bad english )

the messages i get after a while are:

PTS is out of range, dropping buffer
output PTS is out of range, clearing out
input PTS is out of range, trashing
output date isn't PTS date, requesting resampling

the count of getting these messages increases slightly until I get several messages per second.
