First I don't know if this has been discussed before in this forum "mein deutsch sind sehr slecht" and I really wish this was an english forum since much of the dreambox community seems to originate from here. In any case I'm gonna write it again just in case since it helped me alot. I've spent many hours trying to get recording and streaming to work.
As most people with older DB500x boxes know streaming video from the box to a PC works really bad with lots of data loss and bad synchronization of the video as a result. Same goes with recording over the network.
Part of this problem is due to a hardware design error with the Ethernet controller in the box(Asix ax88796). Two capacitors that should be 4.7uF but are on 1uF and therefor limits the Ethernet speed causing packets to be lost. To solve this get two capacitors 4.7uF or greater(I myself used 10uF) and solder them to the existing capacitors marked on the attached image. Make sure you position +- correctly if your capacitor has poles.
Streaming performance from my dreambox(board revision 6) improved drastically after I did this. I don't know which versions of the DB500 that has this design error except that new boxes don't suffer. Try doing a speed test by transferring files with ftp you should get over 20mbit or at least close to 20. I also wrote an email to Dream Multimedia tech support asking for their opinion about this operation quoted reply follows.
