PURPOSE OF RIPPING

statuspending · Member Joined: 30 Jun 2001 Location: st. louis, mo, usa

i want to ask you some questions.
and i want them answered immediately.

i guess im missing a small concept here, which is "why do we rip dvds in the first place?"

isn't ripping the mere copying of data from the dvd to the hard drive? then we go compress that. why don't we just compress it straight from the dvd?

THIS IS HARDCORE

My teachers in school used to say to me "never ask why?"

Anyhow to your "why" question.

I think the ripping is more the "selective" copying/backup(ing) of your DVD. If you have a DVD with multilanguage subtitles, multilanguage audio in DTS, 5.1 , stereo and various extras, but you want just the main movie with an english stereo sound, you'll only rip what you need.

I SEE....

so... when you encode a vob to mpeg2 or what not, it takes the entire damn thing. if the vob is on the dvd, it takes all that commentary and evertyhing with it.

but by creating new vobs identical to the old ones minus a few pieces that we don't want, we are able to create mpegs that contain only what we want eh?

thanks!

We rip to a hard drive first so we don't burn out our DVD-ROM drives. If you rip and compress all in the same operation it takes about 8 hours or so (this is my variable for ripping and compressing to DivX on a 800 meg cd). This will surely burn out a DVD-ROM in no time.

true, this could happen,

but if you look at it like that, then you could also talk about the extra wear'n'tear on the hard drive, which may be more durable, but still costs a lot more than the dvd-rom drives you get for 30 bucks.

Have you ever played a cd or dvd for 8+ hours and felt how hot they become? Hard drives are made for many thousands of hours of use...rarely do ide hard drives on workstations overheat, even when running applications of server functions (ftp, web server, etc.).

Under rare circumstances - I will rip a disc with the intention of re-encoding it (DivX - SVCD, etc)
Lately I've just been ripping the movies to my drive so I can return them to the video store without late fees.
I have a habit of returning a next night rental in like 2 or 3 nights. This way I can get a new release, rip it, and watch it later at my liesure.

It is more than copying... it is also decrypting the CSS encoded data. This feature is not integrated or integrated well in most MPEG-2 --> VCD/SVCD/DivX proggies.

Secondly, the encoding process as others have mentioned takes hours on end. Your DVD-ROM drive is not designed for this wear and tear and will die quite quickly (check out some posts from the doom9's webmaster on his site). The extra hard drive wear and tear is minimal (HDDs are designed to be spinning all the time when on anyway).

Regards.

css encryption and wear'n'tear. you guys are right.

thanks!

as for the $30 dvd drive, http://www.pricewatch.com has 10x for $28, 12x for $31.

keep an eye on the ads from the retail stores...they often have 16x dvdrom drives for like...30 chalupas after mail-in rebates.

are you saying you spend 250 on your dvd-rom drive for your pc or your stand-alone dvd player for your home-theatre??

i forgot the most important thing for me. since i have no standalone, the only way i watch DVDs is through my PC's TV-Out...
and its nice to be able to remove that pesky macrovision when i rip....

deCSS can be done on the run directly from the DVD by FlasK with just a simple plugin; css.mism.flask
I have done many DVD's directly from DVD to MPEG each lasting over 12 hours. None of them gave heat problems.
It just spins-up for a second to read a small block, next the PC needs several minutes to decode/encode and so the DVDRom already can take a rest for minutes, so no reason to heat-up at all.
I use this option for large movies, simply because of a harddisk storage/size problem.

Although this may not have been a problem for you, I have seen several people who have posted that their DVD drives died within 1 and 1/2 years of doing regular ripping in this manner.

In these cases, their DVD drives spin up and some data is read, and never has time to spin down before some more data is accessed --> 10+ hours of constant activity in the DVD drive.

Regards.

http://www.pricewatch.com products are listed at very low price indeed. B..u..t.., do not forget about the shipping fee which can be ridiculous. For example, a 10X DVD-ROM is listed for 27$ (+ 11$ for shipping). So the total is 39$ for a 10X with maybe 5 days waiting for it. Then hope that it works right out the box or else comes in the trouble with RMA.

Other examples are sound cards for 7$ plus 10$ shipping fee.

No intent to turn down this site, I used it a lot myself. My point is: Please mention the price + shipping fee (+tax if appl.) to be more accurate and objective.

what's the best place to find reliability issues? Such as laptop (dell) dvd drive reliability from various manufacturers? Also, couldn't you set the straight-from-dvd compression to be VERY SLOW so that the disc could spin down and perhaps rest for a few seconds, minutes, whatever...say...overnight?
