I think I found it. It seems to have been a bad ethernet cable. I tried testing with the hdhomerun linux client, and I couldn't even see the device. So I moved connections on the switch around, and it worked for a bit, and then started failing again. Finally, I changed ethernet cables to the tuner, and everything seems to be working just fine now.<div>

I can still stream to another client, so it seems like that shouldn't be the problem, but I guess I could change the network topology to see if that fixes it.<div><div></div><div class="h5"><div><br><br><div class="gmail_quote">

</div></div>I'm assuming the HDHR is hooked up to a switch or something, and not<br>
direct to the backend? (Since you can use a seperate Mac client) Has<br>
anything happened to the network card on the backend? Hows its<br>
throughput? I had tons of these sorts of errors when using the built-in<br>
ethernet card on my Asus M2N... though, they were always there, and didn't<br>
start suddenly like yours.<br>
