Random cuts/lines/slices (not interlacing)

[cjv]

Hi,

I am having this weird problem only with CCE, and I'm hoping someone here has experienced this before. In my encodes, these random "slices" or "cuts" are appearing. I can encode the same .avs file twice with the same settings, and each time the cuts appear in different places. They definately do not appear in the source, or in any XviD encodes (which I usually do) from the same .avs.

I have CCE 2.66.01.07 installed on both an Athlon 1400 and my P4 1.4, and the random lines only appear with the Athlon. My gut tells me this has something to do with the VIA chipset. :( Has anyone experienced something like this before?

Things I've tried:
Full system reinstall Win2k SP3
Underclock CPU
Install latest 4-in-1
Encode from C: to D:....encode from C: to C:

Are there any BIOS settings which could contribute to this?
Any suggestions greatly appreciated,

Can you post your avs script.

Hmmm, that's what I thought at first (a bad filter), but the .avs is very basic. I had already eliminated all filters, and it still occurs randomly.

Avisynth 2.07 stable
-------
loadplugin("c:\video\mpeg2dec.dll")
mpeg2source("C:\movie\movie.d2v")
-------

that looks like a decoding problem, possibly due to the computer being not 100% stable.

if you try dropping all your memory timings to their slowest, and also try disabling some other 'performance enhancing' options in the bios, you may come across the problem.

btw, which mobo are you using?

Unfortunately, it's not due to decoding, because if I load the m2v file in dvd2avi, or tmpgenc mpeg tools, the slices are definately there.

I did a "reset to defaults" in the motherboard, and even tried undeclocking 100-200 mhz down to 1333 and 1200. The motherboard is Via KT7a (KT133) with Athlon TBird 1400. I know the combo is known for its share of problems, but I've never had any up until now.

I tried a fresh install of XP SP1, and it has partially solved the problem. I can use avisynth 2.07, but I cannot use avisynth 2.5a. (I believe in my initial tests, I mistakenly had 2.5 installed as well.)

Avisynth 2.5a causes slices, complete system freezes, and BSOD's on XP, and CCE never get's through creating the .vaf. Simply swapping the dll to 2.07 and using the same .avs script allows me to run a 9-pass with perfect results. Very weird. I know it's pre-alpha, and accept that, but it doesn't happen when using XviD, and it doesn't appear anyone else has these sorts of problems with it. (or maybe nobody is using it with CCE?)
