Hello Antti,

Sorry, I'm a couple of days behind on email.

I've received some very mixed results in terms of testing of the patch
(as you can see from the responses).  Even stranger, I received mixed
responses from people with the same boards.  I haven't had a chance to
debug *why* the people who raised problems still had an issue.  I
continue to believe it's the "right fix" but I don't know why those
people reported problems with it.

What do you mean by "mosaic"?  Can you try using dvbstreamer and see
what the overall throughput is?  That will tell us if we are not
getting the whole stream.

You cannot rely on the "alt=n" for DVB.  The max packet size is
determined by an em28xx register.
