[mythtv-users] Tutorial on Encoding (mostly re: file sizes)

i'm buying some of the parts I will need for the MythTV box in the next few days. Our rig will use a primary hard disk for actually running the OS on and a secondary hard disk that will be exclusively for storing data on. Since the main purpose of our machine is for recording / encoding

I am pretty sure that I will encode at 640x480 but don't know about anyother settings or how they will affect file size.For a normal 1-hour show (most of our favorites are this long), what kind of file sizes am I lookingat?This will affect the size of the hard disk I buy for the storage. I doubt

I doubt that you can see the difference between a 720x480 pixel and a 480x480 pixel recording, so I would recommed go down to 480x480 pixels. That saves 25% of the data. If you want to export to DVD you might however consider 720x480 pixels and keep the recordings in MPEG2. Also if you want

When resizing, is it possible to accidentally stretch the image? I saw someone say 480x480 wouldn't be a noticeable difference from 720x480... is the because of the way a TV uses scan lines? On a monitor it seems like it would be very different. I'm curious because I want to transcode HDTV

Others have done a good job of talking about higher end, so let me talk about the lower end. I have Dish network coming in through an anlog line, into my tuner, and out to a 20 regular TV. So my source resolution is lowish, but my line is very clean, and my output device isn't very picky. :) My
