composite or coaxial for hook up

I just got Comcast digital cable. I have had everything hooked up for the last week fine using the coax cable from the digital box to the vcr to the tv. Of course I have all my stereo lines going to my home theater receiver. The sound is perfect. My question is should I use composite video cables to handle my picture or is the regular cable supplied by the cable company just as good. For the record the damn cable box doesn't have a s-video out, I would have to upgrade to a dvr box for that. So that's why I am not going that route. Between the coax and composite which would be better? I have a regular tv, not hd or anything fancy. Would the composite make a noticable difference?
Thanks in advance.
By the wat the Comcast cable modem rocks too, 4mb's baby!!!!!

a coax run is the absolute shittiest way to send that signal. try the composite.

Coax is the worst. Composite is for HD (5 RCA cables= 3 vidio and 2 audio) but better than coax. S-Vidio is good too.

composite is one rca ended cable, you're thinking of component.

Composite is better than a coaxial connection with an F-Type connector, but for today's TV's the Composite and S-Video is about the same when it comes to scan lines. Composite video (1xRCA) has the signal already processed by the device, S-Video the signal is uncompressed to the input and converted on the display. With today's technology the source is already doing a good enough job processing the source that it doesn't matter.

Then if your talking HD component is still not the way to go as of today because it's a compressed signal from the source, a DVI or mDVI would be the best since it's uncompressed and the TV's that use it can interpulate the feed way better than the compressed counterpart in component.

Just a heads up if your going to buy a TV anytime soon buy one with a digital tuner or upgrade to digital cable cause on Dec. 31st 2006 they will be shutting off all "analog" broadcasts making old TV's unusable without a Digital tuner which will cost roughly $100 for off-air broadcasts. This only applys to known sat and digital cable people.

By the way I've got the 6mbps service from comcast, Super Fast.

its not a matter of component being compressed, its that it's analog. you take a digital signal from your hd box convert it to analog component then send it to your digital tv to convert back to digital to display. its too much conversion and introduces error. dvi or hdmi send the signal complete in its digital form which is perfect for digital display devices, and hdmi is backwards compatible to dvi(without audio of course). Not familiar with mDVI, maybe you can explain.

Dealing with this stuff everyday, I would say in your case, just hook them both up and see what you like better. I dont think that you would see that much of a difference without a signal strength meter. Im guessing that your tv has both RCA and F connections. You have many options, if you want to use RCA cables and the F connector you can and you can also hook it up just opposite of that. You should be able to pick these connectors ( RCA to F and F to RCA) up at Home Depot (or similar) If you cant find them, if you are going to be on the ride on the 15th let me know and I will bring you a bunch so you can play with the connections and find the best configuration for you. ( sorry you cant borrow the field strength meter, need it for work)

mDVI was a mini version they came out with that wasn't adopted. I've only seen 2 tv's that had it like 5 years ago.
Also for reference a composite cable is coax with a different type of connector on the end of it. As far as connecting it to the RF connection is what makes it a different signal thus being weaker. So there would be no point to running a Ftype from cable to rca on tv just go rca both ways much cleaner signal.

Vcook, the point you were trying to make with the digital to analog is called a compressed signal. Which is what I said just didn't get into the facts about it.
