TS muxer and audio drift

[drus]

Hello
I'm trying to stream mpeg4 video and mpga audio from linux server to windows client. I have 0.8.6b on server and 0.8.6d on client. I wrote my own module based on v4l module to capture video and audio. Server is a specific device, and video has some delay, about 80ms... So I made such thing: p_sys->i_video_pts = mdate() - 80000;
It works fine, audio and video are syncronized, but after some time (hour or so) audio become choppy.
This is my server command line: input v4l:///dev/video0:size=352x288:vdelay=80000:fps=6.25:adev=/dev/dsp:samplerate=44100:v_bitrate=262144, output #transcode{acodec=mpga,ab=32,channels=2}:std{mux=ts{caching=600},access=rtp{caching=0},dst=10.1.1.1:7128}

I found that TS muxer drops buffer after this message: mux_ts private warning: packet with too strange dts
This message appears frequently, but on client side audio error appear not every time

If I put p_sys->i_video_pts = mdate(); instead of p_sys->i_video_pts = mdate() - 80000; audio is ok, but not sync with video
How to solve this problem? Are there some way to force TS muxer to cache 80ms of audio?
Where I can read documentation on these params of TS muxer: shaping=200000 pcr=70000 dts_delay=400000?

p.s. Sorry for my english %)
