Star Wars Ep4 Region2 Lockup

[bobwillis]

Hi,

I purchased the UK region 2 trilogy today. I thought I'd start backing them up. I started with episode 4.

Whilst analysing the subtitles prior to ripping, D2S locks up. Perhaps someone could confirm this in order to prove my system isn't defective (I did try both my dvd drives).

I then used dvddecrypter (successfully) to decrypt the files to the HDD. I then tried to run these through D2S, but it still locked up at the subtitle analysis stage.

Anyway, the solution is, use dvdshrink (no compression) to decrypt the disc to the hard drive (I kept just the 5.1 audio, main subs & the forced subs). D2S can then process and rip the files that shrink produced with its internal routines. This should cause no sync problems. I will report tomorrow if I have been successful or not.

BTW, I don't know yet if ep5 & 6 behave like this; more info to follow.

Regards,
Bob

Any special reason for not turning off DVD ripping in D2S when you already have it decrypted on the HD? I have never had problems with directly processing output from DVDDecrypter or Shrink.

/add: As DVDDecrypter works, using the DVDDecrypter/vstrip plugin bundled with D2SRoBa should be your simplest solution.

Hi Tylo,

Good news. I've not watched it all yet, but the backup seems to have completed ok. The sync is good and even better news, the Q was 16!
This was one of those discs where a 2% sample estimation gives a first pass size which is well under:

I think it is better to let d2s rip the decrypted HDD files, because sync issues can occur if the title is multi-PGC. This is probably not the case with the shrink files, but I thought it was better to be safe than sorry.

Thanks for the vstrip plugin tip. I don't have it installed at the moment, but I may try it in future.

Bob

Yep, 91.9% on target is too much off. manolito reported that he also had a few large estimation errors, but not with D2SRoBa 3.50 when Jonny's estimation fix was turned off (fix = enabling "Restrict auto i-frame insertion" during analysis in CCE). The latest v3.63 has by default turned off that estimation fix. Could you recover with v3.63, and see if the estimation is better? That means you should get about Q=14, I guess.

Hi Tylo,

I tried using dvddecrypter & the vstrip plugin, but it didn't make any difference. The problem is with the D2S analysis of the subtitles; I have now added the log to my first post. It locks up before the ripping even starts. So it won't make any difference what ripping technique is used; sorry if I was unclear. Running the disc through shrink first, meant that D2S is now able to analyse the subs ok and everything proceeds as normal.

Regards,
Bob

[bobwillis]

Slightly better estimation with v3.63. Like you say, the ideal value would be Q=14,

@ bobwillis

If Jonny's sample estimation fix is turned off, you can generally use a higher value for Adjust %. A value of 2.4 would have given you the desired Q of 14. You might want to try a few more movies with 2.4 and see how this turns out.

Cheers
manolito

[bobwillis]

Hi manolito,

I imagine 2.4 may oversize quite often, but I'll give it a go for my next few encodes. BTW, 2.2 would probably get a Q of 14.

Thanks,
Bob

Hi bobwillis,

sorry to be out of scope,... what kind of turbo-machine do you have? (CCE speed 2.58)

Hi jsoto,

A P4 3.0GHz Northwood in a Gigabyte GA-8IK1100 (Intel 875P) Motherboard with 1.0GB of Dual Channel (2x512) DDR400 RAM. I clock this with a slightly elevated FSB equivalent to 3.2GHz. It goes at speeds of over 3.0RT with NTSC material!

Regards,
Bob

[jsoto]

I've never seen more than 1.4 RT (usually 1.0-1.2)in my P4 2.4 GHz with DVD resolution PAL materials, snif, snif.

A quick note to say that the episode 5 and 6 discs also cause D2S to 'lock up' at the analysing subtitles stage.

Bob
