My 840av is not perfect.

Every 4th or 5th time I switch on I get no response from the built in av. The mic port is also suspect with me having to fiddle with it to make it work.

I now have svideo in.
& sound in.

My svideo in cable has 4 pins & yet the 840av's port has space for 7 pins?

I have not managed to get video out from my rca video out port.

I have just passed up 2 840av's that were on ebay.

I am just spent out at the moment.

I have experimented with recording from tv & indeed the recording is jumpy. Can I make the recording less jumpy?

Will having compression "low" stop the jumpiness?

If you put compression on low, it WILL look less choppy, and almost TV quality. However, uncompressed video takes up a TON of space!!!!!!!! (We're talking about 2 gigs for every half hour)

A single sided, single layer, DVD-R will hold up to 4.7 gigs of data. However, you cannot unfortunately hook a DVD-R burner to your 840AV, because there's no such thing as a SCSI version. Even if you did hook ti up with an ACARD adapter, its doubtful that you'd get it to burn DVDs. Even G3s with quite a bit of muscle have trouble with it.

It's ok, for the sake of argument lets say I have a powerfull computer. I am just wondering the best media for storage.

I would wonder & expect that I could get dvd on my quadra, though dvdr I would expect not.

So at the moment it's a large scsi hard drive or 3.

Why would you expect DVD, a standard which didn't exist until years after your machine was created?

Exactly. My PowerBook 1400 can't do DVD, and i'm not sure how well my iMac would handle it, either. DVD decoding/encoding is a very CPU intensive task.

You'd be better off using a standard DVD player and running the S-Video to the 840av for playthru, but the resolution would be the same as the Q630 series TV/Video System AFAIK. It was horrible on my 660av in terms of an unacceptable 8 bit color depth and it still had an abysmal frame rate, so I put a 5260 mobo in a 630 case until I can set up a new HDD for the 630. Dunno about performance of the 840av with maxed out VRAM, hopefully it's a LOT better than a 660av.

If there's a way to get the 840av to do a better aspect ratio letterboxed display that'd be great. Check out specifics over on fritter: TV/Video System:wasted pixel hack?

Nothing much came in terms of suggestions for a hack over there, maybe I should start a thread over here. The 840av might be a good prospect for a DVD Media Hub if the generic DSP impementation would allow for an aspect ratio hack to work on it and not on the 630.

I have a feeling the dedicated video hardware chipset of a 630/TV/Video System would kick its @$$ at 640x480x16bit and would be a better platform overall. It'd be tough for the av to beat the trayloader, FM/TV Tuner/Remote and form factor advantages, not to mention the major improvement in mass storage that IDE provides for mp3 duty. If there's no way to hack the 630 display it'd still be a no-brainer choice if the 880av is stuck at 640x480 too, even if it could do 24bit, I would think.

cos i'm quite mad a& fairly ignorant.

i still thinkmy 840av could play dvd.

I think the 840av was/is a very well designed computer, better than alot of computers before it & beter than most computers after it.

Your 840av cannot and will not ever decode the dvd standard. A scsi reader will probably hook up and you could use dvd data cds, but never will the 840av play dvd movies unless a player was hooked in through its video ports.

You need to realized that the nubus standard ended around 96'....So there are no expansion cards which can decode dvd. In addition, the procesor in the 840av could never decode dvd. I highly doubt any procesor less than a G3 could decode dvd without some kind of external expansion card doing most of the work.

Your 840av is a great computer...to the extent it was designed for.

Well said.
To back you up on that, you need something like a 400 MHz G3 to decode a DVD in software.
