Playback probs

I am having a couple of problems with mplayer and DVB-T streaming:

I'm not really certain about what it indicates but I get this right before 
mplayer dies.

-snip-
Too many audio packets in the buffer: (4096 in 751616 bytes).
Maybe you are playing a non-interleaved stream/file or the codec failed?
For AVI files, try to force non-interleaved mode with the -ni option.
ds_fill_buffer: EOF reached (stream: video)
A:37422.5 V:37453.4 A-V:-30.885 ct:  5.347  95264/95264   8%  3%  7.7%
1837 0 47 EOF code: 1
-snip-

After the above output I tried with the -ni options but got much the same:

I am running MPlayer CVS (29062004) with the -cache 4096 parameter. 

Exactly the same thing happens too when using dvbstream and mplayer in the 
usual way. Any ideas or pointers?
