[mythtv-users] Garbled video during first minute of capture

Same issue with IVTV 0.8.1.

I don't think it's DMA but I could be wrong.  WHILE recording on 1
tuner, and playing another video on the frontend (FE and BE are the
same machine), I can still obtain this:

tv1 ~ # hdparm -tT /dev/md2

 Timing cached reads:   1184 MB in  2.01 seconds = 589.36 MB/sec
 Timing buffered disk reads:   92 MB in  3.21 seconds =  28.62 MB/sec

I have noticed that is doesn't happen ALL the time, but 80% to 90% of
it.  It has really jacked up trying to process any of the video
externally, and watching the video jacks the A/V sync.  My
installation has worked great since it's first install in March and
now I don't know what to do.

Any other ideas?  Check it out... 7 seconds in.
