one channel has slow video

[James <rjl@lockie.ca>]

I have a Hauppauge WinTV-HVR1250 and a GeForce GTX 650:
01:00.0 VGA compatible controller: NVIDIA Corporation GK107 [GeForce GTX 
650] (rev a1)
05:00.0 Multimedia video controller: Conexant Systems, Inc. CX23885 PCI 
Video and Audio Decoder (rev 02)

I use vlc to play tv.
One of the channels I usually tune to stopped working.
I finally got around to looking at that.
I did another w_scan to make sure the frequency hadn't changed.
I then tried mplayer:

I got audio but the video was really lagged.

After about a minute, the video started working but these messages kept 
getting printed:
> Too many video packets in the buffer: (4096 in 124631948 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.
