NOBODY can figure this out! Im so annoyed at you guys :)

This is the 3rd time im posting this...it seems that nobody can answer this! But just in case some new people are here today:

I can make SVCD's using SmartRipper, DVD2AVI, and TMPEG. This used to take too long...so I decided to use DVD2SVCD. The SVCD's come out perfectly with the Smartripper DVD2AVI Tmpeg method, but when I create them using DVD2SVCD with (Im pretty sure) the same settings, the SVCD video and sound 'skip' every once in a while on my DVD player. This gets annoying because it does it more and more as the movie goes on (on each disc).

Ok...I know this isnt from the disc, and it isnt from my DVD player (and the bitrate is not too high), and it isnt from the burn speed in nero (Ive tried everything!) so.....any ideas?

It's a shot in the dark , BUT : the problem you describe suggest you have a problem WHILE encoding using DVD2SVCD or in other words : Frame Dropping , it seems as if there are other programs running in the background that overwork your pc causing your software to 'slack' every once in while , here's a test , compress your disk then reboot shut down any unnecessery programs , ( all , including anti-virus jokes and Real pests etc) , now use DVD2SVCD to encode , then , prior to burning compare the output video to the one you had previously .
Another way of tackling this is by taking your business elsewhere , simply try this on another pc , and see what happens .
I hope it helps .

DVD2SVCD creates a pretty detailed log file, and some INI files, as well, with settings. Compare these to your manual settings.

Guesses : Field Order, GOP, Bitrate MAX or MIN, IVTC or Forced Film, Audio bitrate. DVD2SVCD uses pretty much the same software you are as I recall, haven't used it in a while. Those log files explained a lot, I remember.

"Once in a While" as in every 5 seconds or 15 minutes? 1 or 2, and/or 3 to 5 skips per half hour, or every 5 minutes, or every hour?

According to the log, my settings are pretty much the same (except the min. bitrate is a little higher on my manual settings, but that shouldnt affect it at all). And "once in a while" means just once in a while. Sometimes its 3 skips one after another within 10 seconds...sometimes its 3 mins apart....but the farther into the disc I get (starts over with each disc within same movie) the closer together and more often the skips get...I know, im not giving you much to work with here, but there isnt much else to say

Somewhere in that log is the difference between what you are doing and what it does. If you want to find out what, here's how.

Start substituting files created manually into the DVD2SVCD process, let DVD2SVCD finish, test for errors. Start halfway in, then halfway forward (if tests OK) or halfway back in the process.

Long and tedious, but only certain way to nail EXACTLY where the process goes wrong. Would yield some interesting information.

What do you mean by

Start substituting files created manually into the DVD2SVCD process

[Nelson37]

DVD2SVCD has a crash recovery procedure which will take up where it left off. You can manually rip a DVD and let DVD2SVCD finish it. Start with rip, then rip + DVD2AVI project, etc. Keep going additional steps until you find the one where if you do it, it plays Ok but if DVD2SVCD does it, you get errors.

For instance, if you rip and process a DVD and it plays OK, then let DVD2SVCD process the VOB's you extracted and that plays OK, BUT if DVD2SVCD does the rip itself and processes it does NOT play, there's your problem.

On that minimum bitrate - TAKE NOTHING FOR GRANTED. Make ALL settings IDENTICAL or you will not isolate the problem. That minimum bitrate could be it. It could be something very minor.

So don't use DVD2SVCD. Problem solved.

[Kingnog]

I like that last suggestion the best

[Nelson37]

That would be the easiest.

BUT - you have here a fairly rare opportunity to pinpoint a problem that may crop up again in the future. It may also help someone else with a similar problem.

You have a straightforward case of 2 similar processes with a slight procedural difference, and a readily repeatable error and correct condition.

It may be a bit tedious to troubleshoot this, but say it leads to a time-saving or quality improvement for you? Or a bug fix for DVD2SVCD?

I should note that this occassional "skip" has been a nagging problem for me, as well as many others. Though as my errors do not increase as the disk plays and are fairly rare it could be something completely different. BUT - I can neither reliably eliminate it or dependably duplicate the condition. As DVD2SVCD was my guide for creating my procedure, you may have my solution.

Could you list IN DETAIL your processing steps, including program versions, for comparison?

I don't understand one thing. How could you loose frames during encoding ? I understand that you can loose frames during capture since you PC have to have enough power do process all the data thata are received, but encoding. I am programmer (but this might work differently) and my program never "skip" some lines in code just because computer is slow.... Only result that I understand is that it will be slower.... Can somebody explain it to me ?
