Not quite following the splitter deal. Looking at the wires right now, the cable wire for my broadband has a splitter on it. The splitter is what my Sharp Aquos LCD is hooked to. It's an "Aneronix" CMCDT2106T-HEP. It also says -120DB RFI and 5-1000MHz The part my TV cable is hooked to is simply called 'Tap'.
I have a few gold looking splitters that the cable company left behind in the event I needed more. Maybe I should try swapping them?
Hard to say without seeing your actual wiring set up. Cable companies typically give out cheap splitters, however on occasion I've gotten decent ones when they were running HD or internet. You can try changing it, it might help if it's better or it might not. What I meant was that every time the signal is split, it's degraded, so any splitters further up the line than the one you're talking about affect it too. On any somewhat modern house, you will have the original cable line that comes to the house which is then usually split in the box on the side of your house. That's the first split in the line. You typically want to keep the number of splits of each of it's line down, preferably to none if you can. Like I said, it's hard to help troubleshoot unless I can see the lines or know exactly how it's set up. If it's really bad you may need to think about getting your house properly wired. The guys the cable company sends out really don't know anything except what they were taught in a class, and it's probably questionable if they even remember any of that.
But anyway, also, another thing to consider is the wire you are using. Low quailty wire adds a lot of noise and degrades signal just like splitters do. If you have any thin, cheapo coax cables, it could help to replace them with higher quality wires. Again, hard to troubleshoot over the internet though.

I have a 50" Hitachi 1080p Plasma in my living room hooked up to Time Warner. Everything works great...
I recently acquired a Sharp Aquos 46" 1080p LCD and I now have broadband internet and 2 HDTV's. I'm starting to believe my signal isn't strong enough to support two HDTV's? I've previously had signal trouble but it's been over a year since I've had any. My Broadband is working fine too, hasn't seemed sluggish but I haven't used my computer at home much lately.
I have the Scientific Atlanta Explorer 8300HDC DVR box. Using HDMI. 480 channels look like garbage, which is not out of the ordinary. However randomly I get small blocks of white that will trail a moving image or the HD channel will freeze until I change the channel and go back. Sounds like a weak signal right?
Also, still images look great - however moving images with Blues & Blacks look like a mess of blue/black hues. But - not all black and blues look bad? Some shots couldn't look any better and makes me question if it's the show... and others make me wish I never spent the money. Is this possibly from a weak signal...or is it why all my buddies told me to get another Plasma?
sounds like you have the same POS DVR box I have for time warner. hard to tell if by a description, but the crappy picture quality you are talking about might be the compression they use for HD over digital cable. I have some HD channels that look decent, one or two that look perfect, and some look lame with artifacts everywhere.
I would think since it's digital cable, if you have any signal at all, you should be fine as far as signal strength goes. you'd either lose all the picture or none, it wouldn't be like getting snow with an older tv if you have a bad signal.
as far as whether the tv is bad or not, you need another HD source. see if you can get HD over the air and see if it looks good.

RE: HDTV troubleshooting?
Ok it does sound like you signal level is bad or at least your wiring is crap
first you should try to only have the first split (buy a multi-way spliter) however many divices need a connection get a spliter with that many
also it sounds like you grounding block isn't grounded (fix that too) the "piss zapped out of me." part
check the type of cable used
RG-56 is the old cable=crap
get atlease RG-6 if not RG-6QS(w/compression fittings)
and if you put in an amp put itbefore the single split
after I partly redid my wiring I went from -8db to +4db (RG-56 stinks)
also the splitters you use should have the correct frequency (satelite "dish to box" needs 2.5ghz) I'm not sure of the range for digital cable
also if you put in an amp also put (rfi/emi) noise suppression on the power for the amp (no point in adding noise)
mine has a single split after the grounding block (most spliters can be used as grounding blocks) and RG-6QS from the Grounding block to the cable modem (cable TV here stinks but their internet is good)
P.S. on the amp look for a Bi-directional amp as a uni-directional will cause problems for your internet
and if you have one really long cable drop that you think needs more power then get a splitting amp

I see what you are saying about the splitters now.
I have lines on a splitter and there is a splitter on those lines with 2 or 3 lines running off it.
So really what I need to do is get a splitter with 6 or 7 outputs for everything. Run the outside cable line into that, then basically wire each TV on it's own line into that splitter. Slap me if I'm wrong.

that 8300hcdvr is 10x better than the crappy moxi box that charter cable offers.

I'd be willing to bet that you've never used it, or else you might not be so willing to say that. The 8300HDC is HORRIBLE. It resets itself whenever it wants, it locks up, it's slow, it deletes your shows when it wants... It's just bad, trust me.

you could do that. or you could get a signal amplifier and put it between the two splitters.
