(Players I have owned/returned/enjoyed/hated from the past: Panasonic 310/320/RV-80/RP-56; Toshiba (very early model--quickly returned due to shimmering and other disappointments--nice remote, though!/6200/3750; Denon 2800; Kenwood 5 disc progressive scan; Pioneer portable; Apex; Malata)


(I favor the Panasonics due to their best bang for the buck.)



Well, I played around with the 4700 for about three hours tonight, testing it with different discs.


Video-wise, I'd say it performs exactly like the 3750 (which I had for a while and returned). I returned the 3750 because I also had a Pansonic RP-56 which I preferred because the picture was a little sharper and the colors were a tad richer. By no means, did the 4700 or the 3750 put out a bad picture. The Panny just edged out the Toshiba in my eyes. (Among the discs I played was "Toy Story" and there was no flicker in the solid reds. I'm not real susceptible to the chroma bug so I can't tell you if it's there. I DO notice combing effects and I didn't see any on the material I viewed. I had a friend watch a few scenes and she thought the Panasonic looked a little sharper also.)


In the box in addition to the manual is a "Supplement for correction" ("Uh-oh, I thought...) In the supplement were some features that appear in the manual and are crossed out due to the fact that these features either never made it into the player or were taken out later.

(Example: "This DVD player uses the NTSC color sytem. PAL signals in a playable disc are converted to NTSC signals to be output. (They cannot be in the progressive output format.) This conversion may cause slight picture deterioration." Everything after the first sentence is crossed out. (Was this player once meant to play PAL discs and convert them? I have a few PAL discs and gave them a try. The player read the disc, BUT the picture was in a continuous roll. The sound was fine as I tried to watch. (for a brief second I thought I had myself a cheaper, but better built Malata on my hands...)


Other statements in the correction supplement help to claify sentences which might prove to be confusing: "The total playing time is not displayed"--the timer is showing the elapsed time and not the TOTAL time of a disc; "The programmed selections will be cleared when you turn off the DVD player." (Programmed tracks of a DVD/CD do not remain in the player's memory when you shut the player off. Does any player do this?)

---The Enhanced Audio Mode does not work for DVD audio discs.

---The clear button does not perform as an exit/enter button.


If you are familiar with the remote from the 6200, you will be right at home with the 4700s. (However it is not backlit nor does it have glow in the dark keys. Gone also is that little wheel/tab on the side that controlled fast forward and reverse modes.) The fast forward and reverse modes are pretty smooth. The Zoom mode is excellent IMHO. It works well and allows you to zoom in nice and tight on some aspect of the picture you want to investigate further. There is a button on the remote to change from interlaced to progressive mode. (There is also a switch on the back of the player.)


Sound wise--well, my receiver is doing all the decoding so it sounds good to me. No built in DTS, but it does have DD. A four page supplement gives guidelines for playback of MP-3 discs.

A cardboard features strip taped to the top of the players states: 10 bit 54 MHz Video DAC with 8:8:8 processing. 540 lines of video resolution. The player can play DVD-Video/DVD-R/CD/VCD/CD-R/CD-W/MP3 and DVD Audio.


What else? Well, all those niffty little features which I never use like strobe, virtual remote, preview, etc. are included. No enhanced black level. (There were some questions about DACs and DVD Audio. I really don't know much about DVD Audio but the manual says sound through the bitstream/audio/PCM jacks range from 44.1 kHz/16bit to 192 kHz/24 bit. Don't know if that helps anybody or not.)


I'll mess around with this player some more, but picture is the deciding factor for me and at this point I prefer the Panasonic even though it has a "flicker-problem" for a very few seconds on a very few discs. To me the 4700 is a 3750 with a better remote, a Dolby Digital decoder (which I won't use), and the ability to play DVD Audio discs (which I don't own). But the price is right for a player that does all this--I picked it up for $250 from a place that doesn't discount its products that much.


I'll be interested to hear what other owners of this player think.

The only progressive DVD player that I've heard of that doesn't have 3:2 pulldown is an older Pioneer model. While 3:2 pulldown isn't explicitly stated on Toshiba's website, I am very confident that the 3750 and 4700 do it.

Yes, it does have 3:2 pulldown.


Mistake on my part in the players I have known--I never had a Kenwood 5 disc progressive player--it was the H/K 50 and I returned it rather quickly because of the shimmering I was seeing.

Can you explain shimmering and what disks I might view to test for this effect. I own the Toshiba 3755 (5 disk progressive player) and i've noticed combing but the picture is quite clear. I can't decide whether to check out the Panasonic RP 56 or keep this Toshiba. My first Toshiba, SD 3109 was great for 2 years then the player began freezing, skipping and exhibiting audio sync problems. I've noticed quite a lot of skipping and freezing with Aliens disk. Is this generally a problematic disk? Can't figure out what to do. I have a warrenty and replaced this player with the SD 3755 but I've heard so much about the Pan RP 56, I don't know whether I should just switch, sight/unseen. Any thoughts?

I also had the SD 3109, but never had a problem with the unit. Sold it last year. Another disk that has a problem with changers is Star Wars Ep1. I have a Denon 3700, 5 disk. When I get to chapter 25-26, I get a disk change (disk #1) I get the same at the end of the extended pod race on disk #2. I assume this is the layer change point. These are the only disks that do this, but my colledtion is small ~35 disks. The disks work fine in the RP56 I just bought.

Thanks for your response. Still wondering about the shimmering issue and if others have purchased the Toshiba SD 3755 player. I'm not sure whether the SD 3750 is the same unit except without the 5 discs? anyone know? The 3755 is quite a solid and heavy unit vs. the Pan RP 56. Not sure whether weight plays a factor. Probably not. I suppose it's the sage chip in the RP 56 that lends to the excellent quality that I've heard so much about but haven't yet seen. Still can't get the good guys to display this unit and I was trying to avoid going out and buying one just for test purposes.


And anyone else have comments about these Toshiba players, namely the SD 3755? thanks for all your aniticipated help.

"Shimmering"--well, I use these discs to really spot it.


"Rush Hour"--Scene--Going To The Show--when Chris Carter walks in and out of the Captain's office--see how straight the blinds are--if they're "moving", your player is having a problem handling the scene--The beginning of the next scene--the brick, red building when the corvette pulls up--are the bricks moving?


"Seventh Seal"--Second scene--the shoreline, the knight's chainmail


Basically anything that has lots of straight lines or plaids


I understand that "Titanic" is a real torture test, also, but I don't own it.


In progressive mode the current Toshibas and Panasonics don't have a problem with these scenes.

Does anyone know what chipset the 4700s and 3750s are using? Is it the Genesis Chip?


It seems that many reviewers like the Sage in the RP-56 best around this price point, but people are mentioning that they like the features better in the Toshibas (3750/4700). Besides the DVD-A in the 4700, what features make the Toshiba stand out over the Panasonic?


(going to be buying one or the other with my 36" Toshiba HDTV flat-screen)

Franchot (or any other 4700 owners),


You mentioned that it came with "A four page supplement gives guidelines for playback of MP-3 discs". I was wondering if you have any mp3 discs, and if so, whether you've tested this aspect of the player at all? Or, if you don't have any mp3 discs, maybe the supplement that you mentioned gives some info regarding the questions I have:


#1. How is the sound quality? I know this depends on how the MP3 was recorded, but would you say there's a 'minimum bitrate' at which is sounds good/acceptable on the 4700?

#2. Does it show either the file title, or the ID3 tag, on either the player's display or on-screen?

#3. Can you FFWD or REW through a single MP3?

#4. Can you skip to a particular MP3, just like you can skip to/over a particular track on a CD?

#5. Does the 4700 support 'random play' of an MP3 disc?

#6. Does the 4700 support program/playlist for an MP3 disc? If so, up to how many songs?

#7. any other helpful comments?


Thanks so much for any answers to any of these questions.

I picked the 4700 up last weekend, but haven't had a chance to use it much so I can't offer a lot of feedback yet, but...


The supplement refered to states that the MP3 must be of a certain bitrate in order to play. Of course, I can't remember what it is right now. I'll look whenI get home tomorrow. I'll also try out some different MP3s to try to answer some more of your questions.

team_slug,


thanks. any info you could provide would really help me to make a more informed buying decision.


FYI, before asking, I did try to find out some info on my own. I went to Toshiba's website, to the page where they have the manuals posted http://tacpservice.toshiba.com/Consu...uals/dvdct.htm . However, if you go there you'll notice that the 4700 is still not listed there (at least as of the time of this posting).


So, thanks for any info you can provide.

What were the 'various reasons'? I'm not nuts about the looks of the Panny but I ended up buying it for the Sage chip. I don't see myself spending much cash on DVD-A's that I can only listen to in my theatre room, which is why I didn't go for the 4700. Will let you know what I think after watching it.

I too like the sage chip in the RP56 but I thought the colors, blacks and contrast was better on the SD4700. In addition the SD4700 has a lot of nice features: CD/DVD text ( you have to manually select it everytime you put in a new disc, which is a pain), better audio capabilities.


In addition I got the SD4700 at Best Buy for $209, open box, so I took back the RP56 and bought the SD4700. The open box SD4700 was purchased on Saturday and returned on Sunday.


But, I still haven't forgotten that Sage De-interlacer. I wish the SD4700 had the Sage Chip, that would really be nice. I'm sure it would push the price of the SD4700 up.

I have been trying to get a good MP3 playback on this for 2 days now and have a couple more things to try..like a different encoder and different media types..but so far no luck getting anything resembling quality from the 4700 mp3 playback. I have tried blue and silver CD-R media with bitrates 128, 144, 160, 192, 224, 256, and 320, and all my mp3 files are played back with a terrible artifact that sounds a bit like an echo on punchy areas of the recording. Hard to describe really. They sound perfect on a PC though. I am using EAC http://www.exactaudiocopy.de to rip and RazorLame to encode. I think I am using version 3.89 which is a beta version of the lame enocoder.

This may sound ridiculous but I am incredibly suspect of Toshiba products these days. I had a Toshiba TV (with Carver surround) and a Toshiba VCR (MF-845) that I bought in 1992. I cannot begin to tell you what incredible quality and durability they had. They still work although I gave them to family and got some better components.


Bought a Toshiba DVD player a few years ago. Couldn't play CDRs well and was just junky overall, lousy build, etc. I truly believe that the quality of their products are undermined. I'm not confident in their ability to read multiple formats and have heard too many accounts of the same problem with the Toshiba line. I can't account for many people who like their equipment on epinions but others on audio review noted problems with MP3s.


That said, I opted to get the Panasonic RP91k for twice the price at $450. Why? Because I saw it in the store and people swore it was well justified over many other products. Additionally, after hearing all the debugging that has been commonplace on these units I decided that the RP91 had been out a bit longer, didn't have the chroma bug, and had time to work out all the kinks that were not in the player. Decided on an additional 3 year parts warranty (on site) for $90 which was nice although I rarely get them. I could be wrong, but I'm wondering why these units which just came out dropped in MSRP in half.
