JVC M10 and DVD Ram

[ejai]

I was wondering if anyone noticed what I have when it comes to using the dvd-ram and the JVC M10. What happens is the I consistantly get artifacts in the video stream when using the dvd-ram disks and none when using the dvd-rw.

This doesn't happen if I use the Panasonic recroder, the ram works fine. It seem to me that the JVC was made to do -RW and dvd-ram was an after thought. This does not create a problem because I prefer to use the -RW to capture video and sometimes I use the ram for testing.

I was wondering if anyone else noticed this, also I do own 2 JVC M10s and they both do the same thing.

I've been using both -RW and RAM to do some tests on NFL football games this preseason. I set both for FR-180 (3hr) mode and to me the -RW recordings look better.

The wide shots where there is alot of movement, seem to have more artifacts on the RAM recordings. I like using RAM since if I get home late I can watch the game while the recording is still in progress but not sure I'm going to use it.

The down side is if I want to save the game, edit and re-author on the PC it would have to be re-encoded since 480x480 the RAM uses isn't a standard DVD resolution. More quality loss there probably. I guess what I really needed was a hard drive recorder, but I didn't want to spend the money and with Dual Layer recorders coming, a more expensive machine didn't make sense to me.

As a replacement for my PC capture device for VHS transfers, and for DVD movie playback I'm very pleased with the $300 I spent on the DR-M10. It would be great however if it was Dual Layer so I could get SP quality on a 3-3.5hr NFL game.

I've seen lots and lots of RAM problems. I've talked about it in the big JVC thread a bit.

I agree Lordsmurf, there is definately something wrong with how the JVC handles dvd-ram video. I'm not talking about macro blocks on fast movement, that can happen on a -rw as well. What I am talking about is a scene would break up into block noise as if the stream was interrupted. The funny thing is that it doesn't happen in the same place twice in most cases, which makes me think that is has very little to do with the source but with the JVC's ram recording function.

As I said before I use the -rw more than the ram, but the way the ram is working in the JVC M10 it might have been better left out all together. If I must make a ram recording I prefer and have no other choice than to use my Panasonic recorder, (but that rarely ever happens).

Just an observation.

I've just bought a Sony muti-format dvd + PC burner that is dual layer compatible. I did this because I was using the Pioneer A03 and the ram transfering to the PC was too slow. After Lordsmurf had brought this to my attention I bought the new burner and the -rw is much faster than the old A03.

I'm still waiting for the dual layer media to come down in price before I purchase any. 8)

I've noticed problems on RAM that neither of my Panasonic recorders had too. I thought maybe it was just the last batch of discs I got, but I guess not. This makes the JVC go way down in my book since I have almost 200 RAMs, most of them double sided.

Panasonic tends to make corrupt files itself, so it's not flawless. I've dealt with more of those kinds of discs than I care to think about.

My experience with Panasonic recorders and ram have been very good. I have made at least 500 disks using the Panasonic using ram. I've never really had a problem, I would capture using the Panasonic and author using the computer.

My only concern was the 25-30 minute transfer time from the dvd-ram to the computer hard drive.

I'm using the -rw mostly because of the speed but I must admit I do miss the ability to watch the video from the beginning while recording. The JVC does a terrible job of encoding ram, in my opinion if you want to continue using ram go elsewhere.

I still have my E10 and it still works like day one, so I guess I'll be doing the RAMs on it. The drawbacks are that it only records 2 hrs per disc, I used to get 2hrs 9min on the E20, I think the JVC is about the same. It's also in the bedroom with wires everywhere since it has the built in Dolby Digital decoder. I have to move it to the living room to record, pain in the ass. I'm beginning to like the JVC a little less every day it seems like, maybe should have gone with Toshiba. I've never owned anything Toshiba in my life, always thought of it as cheap, but I don't know about JVC anymore either.

I feel your pain, I still use the JVC quite a bit but I turn it off after 3 hours of use due to fact I am not sold on it's durability. The heat issue that seems to be a big concern to some JVC users makes even me a bit uncomfortable.

My Panasonic works well in all conditions, and believe me it has been through hell. It still works great. I love the picture quality of the JVC, but I have some issues with this recorder. Its being sold as a dvd-ram recorder but it's really a dvd-rw recorder.

I use mine for a disc then give it a break too. I do like the recording from the satellite to DVD-R, but it darkens videotape recordings a little too much for me. It's cleaner recording from videotape than the Panasonic was, but the Panasonic made the copy alot closer to the original as far as brightness, contrast and color are concerned.

I couldn't of said it better

That's why I use video enhancers with the JVC in order to get the right balance of color and brightness.

[samijubal]

Where do you get one of those and how much do they cost? Any certain brands/models that are better than others. I have hundreds of videotapes.

I got mine on ebay for 40 bucks. Just search for video enhancers.
