I misread what you said about Netflix. I thought it said Mediafly has problems as does Netflix. You could still try hooking up the Roku directly to your modem to see what effect it has on Mediafly.
You could try my
speedtest channel and see what kind of throughput it shows. It's not the most reliable measure, but I generally get very consistent results and when they start to become inconsistent I know something is wrong. My XDS box suddenly developed a wireless issue while my original N1000 had none, but I live in a congested area so I suspect a neighbor is creating some kind of interference. It's strange that the N1000 can handle it with no problem but the XDS can't.
I still can't imagine how you could have problems streaming from your server with a wired connection unless it's really a video problem. There might be two separate issues here - one that affects Mediafly and one that affects your videos. I think the original box had about 64 Meg of RAM and the new ones have even more, so if your videos are shorter than that I would think they would be pretty much downloaded completely shortly after the video starts playing.
I'd also say it's not unusual for my boxes to get into some kind of strange state where only a reboot will fix things. Also, don't forget that having too many channels can cause strange things to happen.
