Only way to see is try one. However, it will take a LONG time to convert the file, so don't expect just to burn it and be done with it. I'm sure you couldn't fit more than two movies on it. It's similar to how an audio cd works. A cd holds 650mb and each mp3 is 4mb, so it should hold lot's of music right? Wrong, once the music is converted so a normal music player can use it, you can only fit on avg 13 songs. The length of the music/movie then makes the difference.
Seriously, its worth your while just to buy a DIVX playing player. If you look, they can be had for less than $50. It'll save you the hassle of converting (takes a long time plus there will be many codec issues that may pop up with AVI files actually encompassing dozesn of different formats with different codecs). It'll also save you DVDs as you will be able to fit it straight as a 700MB divx versus the converted movie into Mpeg2 (DVD format) which might be a few gigabytes and still be as low quality as the original divx source.
I have a new computer so encoding is not a big deal for me, but if your computer is older it may slow everything down while you encode and it will take longer...
I use a program called divxtodvd or its also called ConvertXtodvd. Works very well for converting movies. However you will not be able to fit multiple movies onto a dvd.. Well you could, but you will lose quality.. When you convert a movie it makes the file much much larger.. On divx to dvd you can set the size you want and try it. It takes me about 30 minutes to convert a movie to dvd format. So get divxtodvd and try it out. Try setting the size in options when you convert so you can put two movies on one dvd and see how it works, maybe the quality won't decrease much.. You can set divxtodvd to burn automatically after encoding as well..
They've got 50 and 75 footers at monoprice as well. I just run my sound from an old generic soundblaster and it sounds fine... it's not 5.1 DD, but it does the trick.
I ran an svideo cable to my old TV from my comp and it was a good picture to. I don't know, I just found it a heck of a lot easier than trying to get burned movies to play on a finicky dvd player... although I didn't have a divx dvd player.
If you need a hand with hardware or software issues, just PM me.
50 Foot S-video cable and an adapter for my headphone jack with some long RCA cables and I'm rockin away.
Now I only wish I had a widescreen TV instead of my old Sony Trinitron.
All of my downloads are in Wide screen format so I am losing about 1/4 of the screen or more in the transition.
Maybe time to talk to the wife about getting a LCD.........
for the audio, i used to use a cable that would go from the headphone jack from my speakers, and then the same cable splits into two left and right RCA audio cables, that you can plus right into the back of your tv (i had a sony trinitron as well) and it worked great for audio, just put the volume on max on your computer and then use your tv volume to adjust, bought the cable from the source
