Ah. well I found out that my card and drivers can only handle 800x600, I think. Although I downloaded TVTool, to enlarge the screen a bit. The problem wasnt the resolution, it was that annoying frame around the "screen", which the "full screen" function of TVTool eliminates by zooming in a bit. Yeah, so i lose maybe half an inch around the edges because it adjusts it for overscan, but it looks a hell of alot better. Oh, and the TV chip on my GeForce2 is a Chrontel.

Just some insight.. may be helpful or not.

Anything you display on TV has been sent out of the video card at 720x486 because that's the native 'resolution' of a 4:3 NTSC tv screen (or a VCR if you're just doing slave recording). Your desktop size determines how much content is on the screen, but it doesn't really increase/decrease the signal that the TV itself displays. The computer will operate at 1024x768, you will perceive 1024x768, but the video card will stretch/shrink the image down to 720 before the TV displays it. A monitor doesn't do this, it actually recalibrates/[multi]synchs the RGB guns so that the scan rate changes. TVs lack this ability because they run at a single scan rate (fixed frequency vs multi freq/synch monitors).

When doing TV out for recording purposes, I recommend that the video resolution is changed to resolution closest to 720x48#. It seems counterintuitive, but you get a better image because the video hardware will no longer be scaling the displayed image to match what the TV can accept. Unless you're working with DV material (and then you would be using a dedicated DV in/out box so this is all moot), chances are your codec is already stretching your video to full screensize. If the codec is scaling to 1024x768, then the hardware scales that same signal right back down to 720x486, you add artifacts and also lose sharpness.

I'm not aiming to start more flames so I'm not going to respond after this (if you respond), but you guys have some attitude issues here. I tried to contribute potentially relevant information that others might find useful concerning the subject. This forum doesn't seem to get much traffic as it is, if you want to keep it that way, I'm happy to oblige..

Also, I started fansubbing in '96. I'm only a noob to this board.

Fuck your righteous attitude, man. So what if you were fansubbing in 96. We dont have attitude issues. You have issues with our attitude, why should we change it to suit you?

WHAT IS WITH NOOBS THROWING THEIR WEIGHT AROUND???

Fucking necroposting crackheads... If a topic is over 2 weeks old, don't dredge the shit up. If it hasn't recieved a reply in that long, its intuitive that the original question has been answered. Stupid fuckwads then try to be self righteous about the shit... God I hate the summer noob influx.
