What is the video service you are using for your HD DVR? If it's an IPTV source, your stream speed will be affected adveresely.
When at work my stream speed is 600k+ and works fine when I choose coax for my video input, but if I choose my HD DVR as my video input the stream drops to well under 100k and won't work - Is that normal? Seems like a slow stream speed to me. Shouldn't the stream from the component be around the same speed as the coax? It can't be my internet connection can it (Considering the coax stream speed)?

Time warner cable coax in to a Scientific Atlanta Explorer 8300, and I'm using the Slingbox HD Connect cable to grab the stream. From home (on the local network) there's no problem as the sream speeds start at 1500kbps and build fairly quickly to 5000kbps. I guess that means that the dvr and Slingbox are OK. Could it be that the component input packets are different and they are colliding or mis-routing on the network once they get to the Linksys WRT54g or the Scientific Atlanta DPX2203 cable modem? I just don't see why the component stream would be any different than the coax stream...

Ah ha... You are using cable internet along with an HD cable source. All the digital bits are traveling on the same cable into and out of your house. When you watch an HD source you are transmitting over 4-5 times the data over the wire versus standard def cable. And actually, standard Def Cable might even be analogue to have no overhead at all. So, when you you turn on the HD DVR, your bandwidth shrinks to a teeny tiny amount. Not enough to do a Sling Stream as well as watching the DVR.
Do a internet speed test and compare your speeds before you have the HD DVR on and with it on. You should see a big difference in speeds.

Great concept, but I get the same speeds and responses whether the HD DVR is on or not.
DSLReports - Speakeasy Sever 386 miles away:
10187kb/s down - 725kb/s up while viewing HD programing.
13684kb/s down - 713kb/s up while HD box is powered off.
Speedtest.net - server in same state (Ohio):
11674kb/s down - 723kb/s up while viewing HD programing.
10937kb/s down - 732kb/s up while HD box is powered off.
Any thoughts? I appreciate your help!

Uh, nice try but not correct.
CATV channel frequencies and Internet frequencies on cable are completely different and segregated. Watching an HD channel will not affect your internet speeds. Your theory is just completely incorrect.
Phil, you are usually pretty good at technical comments. I'm surprised at this one...
And since the HD slingbox has not been released yet, all inputs to current Slingboxes are SD with the exception of the Pro using the HD connect cable. The pro then downconverts the video to SD.
So no matter what, with today's products, you only stream in SD and in fact when streaming remotely you stream in half of SD (320 x 240) unless you manually crank up the bit stream.
Why he's getting a slower bit rate from different inputs is a mystery to me. You really shouldn't. Maybe something is amiss with your Slingbox. I would try rebooting it and see if that helps.

Rebooted - same issue. Tried to access from multiple locations - same result - coax OK, but component a no-go with a stream under 100k.
I'm thinking that the point of failure has to be the router or cable modem, but there would have to be differences in the packets for those appliances to handle them differently, no?

There is no difference in packets in the way that you are thinking about them. Sounds like you might have a bad Slingbox. I'd call Slingmedia. It happens.
