I've even had them plugged directly into each other and both plugged into a switch without the router, so they'd form their own p2p network and use their own settings. Same results no matter how i've done it.
In about 2.5 days, one of the receivers MRV server just stops responding to mrv or directv2pc requests. The client on that receiver keeps working for a while. If I let it slide for a few hours, eventually that receiver with the flaked out MRV server will grind to a halt and freeze. Sometimes its one receiver, sometimes the other.
Sometimes turning mrv off and on from the misc menu makes the server come back online. Lately though that just spurs it along to freeze during the off/on process.
MRV worked fine for me, except for the bug where the playlist jumped back to the top all the time, for the first ~4 weeks. Just the last 4 that its been doing this.
Thats the first leg, the friday night to monday afternoon. I reboot both receivers and they last longer on the second leg, usually until sometime thursday or even friday morning before one of the MRV servers drops off.
On one release about 3 weeks ago, the MRV server had a hard time staying up for more than an hour or two, same symptoms.
This, and the splats, are common issues with both receivers, utilizing three different switches (my asus routers switch, a rock solid netgear 10/100 and the new netgear gigabit switch), and I've tested and swapped the cables around. No real change in the behavior.
I've even used the cables at gigabit speeds between two pc's with no errors or problems transferring huge amounts of data back and forth.
