[mpeg2] Re: Transport Stream from MPEG2 encoder card

[Bram Stolk <bram@sara.nl>]

Klaus,

Make sure you are using the CVS version of the driver.
I can tell you that it works fine with a 2.4.18 kernel.

If you keep having problems, you might consider moving PCI slots,
but I don't think that is an issue, as your 1st recording is always
OK.

Also, I will post the latest FAQ on this list, which may help you.

   Bram
