Ripping and encoding speeds are falling

[dacow]

Dear all,

I've read all forums however noone seems to have the same problem. It might not be directly related to DVD2SVCD, however I just want to know if anyone else has experienced something like that.

My PC config is AthlonXP 1800+, 256Mb RAM, SAMSUNG DVD/CDRW 32x, 7200rpm HDD.

I did reformat my HDD, installed WinXP SP1, latest ASPI, DVD2SVCD and CCE2.5. Ripping speed was 8-10k, CCE encoding speed was 1.6. Then each next 2-3 days the speed of ripping was falling 1-2k (first 6k, then 4k, now 2k) and speed of CCE encoding was falling too (1.4, 1.2, 0.9 and now 0.7). Of course the results are from the same movie (tried several).

Then I reinstall everything once again (tried XP and Win2K) and the results are the SAME :( First day the speed is good, then it just goes down and stays at 2k ripping and 0.7 CCE encoding). I have NO CLUE where to look. Now I reinstall my system every 3 days :)

PS. No, it's not a virus, I've tried all antiviruses with latest updates. Also, did disk defrag every day - no change.

Hm..that's interesting.
After you formated and installed everything, did you happen to reboot your computer between encodes?
I had a sort of the same problem. Then after a reboot, everything came back to their orginal speed.

winxp is the culprit...I reverted back to win2000 because of it. It'll switch your ide channels from DMA to PIO mode out of the blue.

Win2k + new DVD firmware helped, it's stable now, 6k ripping, 1.6 CCE encoding. Phew... :)

I've a Dell machine with Lite-on dvd and cd r/w drives and use XP Pro. After a reload from a crash, I noticed my ATI diagnostic said 'no dma on DVD suggest enabling'.
I followed all the threads (there aren't many) at the Intel site, and the Microsoft site.
read: http://support.microsoft.com/default.aspx?scid=kb;EN-US;310751
it says theres a tab setting to adjust.
But there isn't. why? Intels LATEST chipset accelerator for my particular box has now automated this. However it doesn't report the DMA setting as it did before. They have a util:
http://www.intel.com/support/chipsets/iaa/ec2.htm
that will tell you what the settings are truly set at. Unfortunately a number of programs/utils I have dont seem to read the state correctly. I have no solve as yet for this, but a case number from ATI and there promise that they're working on correcting this issue. There is a reg entry that may affect this for some folks but I caution VERY strongly about touching this unless your at wits end.

also, there is a util that undoes the switching from DMA to PIO that XP does and resets it back to DMA as default called 'pushdma2.exe'.

Where do I get pushdma2.exe ?

Also, for VIA chipset, which I have, it is recommended to install latest IDE driver from www.viaarena.com. Some say it prevents XP from switching to PIO mode.

I havent actually found any probs with my win xp reverting ide channels back to pio mode. I'm using an intel chipset board with a p3 cpu. One thing i did notice in the past which was heavily discussed at cdfreaks in the clone cd forum was how intel ultra ata drivers never actually work the way they should. I found personally that with the intel drivers, i was either burning coasters 2/3 times or that my 36x writer was burning at a max speed of 12x. I know its not directly related but it could be a consideration as I now only use the native dma drivers that come packaged with win xp or win2000 (sp3). They seem to work fine as far as cd burning goes and so i can assume the same would apply for ripping the vobs from dvd's.
