[mpeg2] Re: kfir MPEG 2 Board

["Rob Morris" <rmorris@cdlsystems.com>]

There is another solution by Sensoray based on Stream-machine chip.
We have used both the Kfir and the sensoray board on RH 7.2
http://www.sensoray.com/html/616data.htm

There are a couple of differences. I would say the Sensoray/Stream machine
does a bit better job of encoding, but that may be subjective.
Sensoray is more $$.
Sensoray also does decoding.
Kfir behaves strangely if you remove your video source.

Being a commercial product (you would think) Sensoray is doing a bit more to
support their driver.
At this time, the driver is a bit flaky, but have got it to work. They are
working on making it better.
