Hi, sorry but I can't follow your argumentation. I really mean what I say. If 
you run the DVB Drivers under very high system load the read(demux,...) 
occasionally returns an error (I think it is EOVERFLOW). I would really like 
to know if such overflows can be avoided using larger buffers for the driver. 
On the application side I do use a large ring-buffer and an extra IO thread.

Yours Jürgen

P.S. are you unhappy with the current drivers? I have no choice for the 2.6 
Kernel - I already had difficulties to migrate your 1.1.7 drivers to the 
2.4.19 and later kernels (changes in i2c). You might be insterrested to know 
that a lot of people still load the patched 1.1.7 drivers from my web-site 
(about 10 per week). J.
