Disabling Write-Behind Caching in WinXP

[stagman]

Hi all, i got Videostudio 8 with my DV-IEEE1394 capture card, installed ok and can capture/edit/create video files and DCVs. But, when 2 out of 8 files on DVD go out of sync with video/audio and video jumps, i checked my pc settings as in user guide. All was ok but I couldn't change 'disabling write-behind caching' as instructed as the option was 'greyed out'. So I went to :
'My Computer>System Properties>Advanced Tab>Performance Settings>Advanced Tab>'
and changed Memory Usage from Programs to System Cache. The reason for this is if you click on Help for these 2 options, it is explained that for Programs memory uses XPs default cache but for System Cache, memory uses a larger cache for programs that need it. Have I done right or is there another reason for this intermittent video corruption. Please don't say upgrade to ver 9 or 10. Cheers

Can you post how you created the mpeg2 files and burnt the dvd?
The captured video (dv.avi) files played correctly?
If you edited MPEG2 video files using VS8 then I would suggest give up editing mpeg2 video files using version 8 and upgrade to 9 or 10+

The mpeg2 files were created by changing Project Properties from avi to mpeg2 24bit, 720*576, lower field 1st.

Ultra DMA 5- Ultra100 is enabled on my SPP/IGP ATA controller (by default).
I've doubled my swap file paging size to the maxm allowed - 1536Mb
( 512 RAM).

I noticed that some files were 16:9 format and a couple 4:3. I've changed them all to the latter and I've yet to make another DVD.

As I said, I'm reluctant to upgrade unless there is conclusive necessity.
Cheers,

Cheers, Kenneth, I'll check all these. BUT I only have one 200gb HD and I couldn't disable 'write-behind cache' as the option was 'greyed out'. I will delete the temp and convert files, though and retry now I've corrected the 4:3 format as posted above.

Thanks for replying,

are you sure that you double clicked disc drive and then choose your hard drive (normally C:) after going to device manager?

Yes, I did, Kenneth. It's greyed out.

Following on from my previous reply and 4:3 and 16:9 aspect ratios.

After making them all the same (4:3 in this case) - DVD video problem gone!

Thanks for your help guys.

All versions of VideoStudio have had this problem or that. There's no guarantee that upgrading will get rid of problems. VS8 worked fine for me, to the point where I hesitated long before actually moving on to VS9. I like VS9 better, but not because of "lack of problems" but rather for certain features.
