Frequently asked questions

Some answer to frequently asked questions

  1. Using Multiple cards

    2. In order to use multiple cards with MuMuDVB you just have to launch one process per card

  2. Network flooding

    3. If MuMuDVB floads your network it can be:

    • You have a HP switch which doesn't support data driven IGMP

      • See the full doc

    • Your switch doesn't support multicast/IGMP

      • Use unicast or another switch

    • There is no multicast querier on your network

      • Look to the manual of your switch. You need one IGMP querier on your network to have multicast working. This option can be disabled by default.

  3. Error : DVR Read error : Value too large for defined data type

    4. The driver of the DVB card have a buffer for the incoming data, waiting for the userspace application to read it. This message appears when this buffer is full and the driver had to trow data. This message is not important if it doesn't appear too often. If it appears too often, there is probably something which slow downs your system.
