[mythtv] More on saa7134 + v4l2

Here is an update on using v4l2-old + saa7134 with mythtv

I have managed to get a picture out of it (used v4lctl to set to 
composite input), no code changes were necessary, defining V4L2 was 
enough, however if have a couple of issues:

If I use 640x480 the picture is virtually live but it drops 3-5 frames a 
second using both rtjpeg or mpeg4  (I have a Duron 1.2 and rtjpeg uses 
less than 10%)

Using 320x240 I get no dropped frames but the picture lags the actual 
feed by about 5 seconds.

X is running at 640x480 using the Nvidia NVdriver binary driver.

Specifying a resolution somewhere in between will cause a seg fault most 
of the time, especially if the aspect is wrong.

I am using todays CVS.


Any suggestions are welcome.
