Blockiness, but only after approx 3/4 way thru disk

[Jono]

Hi,

I am a newbie and have been trying to rip PAL VCD's from DVD's using Smartripper / DVD2AVI / TMPGEnc / Nero. Everything seems to work just fine and I can watch the movie on my Pioneer 535 player. However, after about 3/4 of the disk has been viewed, it starts getting more and more blocky until it is unwatchable (tried it on "The Matrix" and "6th Day". What's even wierder is that if I turn the player off and fast-forward to that portion of the film, it seems to play just fine. Is it possible that the DVD player memory gets more and more corrupted as a film is viewed, or should I use different ripping software or settings? Thanks !

I am new to making SVCD's in NTSC format, and am having this exact same problem of blockiness about 3/4 way through the disc. I am using NTI CD Creator Version 5 as my burning software. I am playing the discs on an Audiovox 1680 portable DVD player. Can anyone out there shed any light on what might be causing this? Thanks.

Have you tried playing the discs on your computer? Try that and see what happens. If it has the same degeneration you will know that there is something wrong in the creation process....if not, it is the DVD player....

Thanks for your post. Whilst I was waiting for an answer on my post I spent an extra hour or so trawling around the other messages out there. One of them suggested that CD media may be the culprit for general video coruption. I must admit that the CD-R's I'm using are fairly cheap, so I have now tried it with a branded CD-RW disk instead (as this was mentioned in the post). I have only tried it with one film (Matrix), but the result seems to be PERFECT. Maybe standalone DVD players are more fussy about media types than other CD devices. I'll hold judgement until I've written a few more CD-RW disks, but looks promising (even if CD-RW's are more expensive than CD-R disks).

A lot of dvd players don't like some CDR brands like the new maxells in the slim cases and green pakaging. Those always skip near the end. Avoid crappy media like that.

Thanks for the post. I've now tried what you suggested and got an interesting result. The CD-R VCD seems to play OK in the CD rewriter drive of my PC, but it won't play at all in my computer's DVD drive (although a CD-RW disk of the same film did play in that drive). So I think this shows that the media may be to blame (see my seperate post to Prendee).
What I ideally need to do now (to prove your theory) is watch the whole CD-R disk thru on my PC to the point where it should go wrong (about 45 mins into disk). However, I've tested the Matrix film so many times in the last few days that I'm now thoroughly sick of it. I'll leave it a few days before I try that one! Hopefully when I try some other films on decent CD-RW media I'll be able to prove it that way instead. Thanks for your help.

Jono.

Some disks cause problems with psx, music, mp3 etc but it matters even more what speed you write the disks i find if i write at 4x on my 8x burner and use decent cd/r disks verbatim etc and not some unbranded rubbish of the local car boot or computer show the films should be fine.

Flid,

I'd already thought to try the different speeds on my CD writer (I tried 4x and 2x on my 8-speed writer), but this made no difference. However, I take your point about buying decent branded CD-R's, so I'll try that before spending lots of money on CD-RW disks. Thanks for the tip.
