Hi,
ATM, I'm unsure if there's something wrong lately with my system, because I found out that I suddenly have jerky playback of XVid or DivX movies beacause of high CPU load. I know that there may be a hundred reasons for this, though it's not easy for me to find out, for the system in total is running without problems.
So, at first I want to make sure that this is really an error and not "natural".
I'm running XP on a PIII unit @ 667MHz,
256MB RAM, main background programmes besides the usual services I haven't been tampering with: Tiny Personal Firewall, AntiVir.
WinDVD4 never exceeds 75-80% CPU capacity on 4:3 fullscreen, daylight scenes, no stills.
But Xvid or DivX decoding - w/ or ... \w (without?) ffdshow in the filter chain - it takes basically ~50/60% on totally black frames with only some letters ("presenting...."), a usual case at the beginning of a movie, and quickly rises to 99% on daylight scenes, already on 16:9 movies.
Quality with the original postprocessing filters, both Xvid and DivX 5.02, is set to lowest (=speed).
There's no difference if run from HD or CD with all drives on DMA transfer rates.
I've "converted" from W98SE to XP a few months ago an cannot remember having had problems with playback so far.
AGP runs at 4x66MHz with my TNT2 pro (anyway WinDVD is doing a good job!).
Latest XVid installed, also OGG-DSF. But it's the same problem with Avi files.
I raised gamma preset on startup for my video card, but I refuse to believe that it produces extra load on video decoding.
One of the latest installations was the firewall and the Antivirus programme. But I doubt that it interferes much with the Direct show system or whatever is to blame.
Oh, I forgot: I tested with bsplayer and Zoomplayer with the latter being more reliable in stability, but no differences revealed.
Any help would be appreciated, guys, because an essential part of my daylife is missing: ATM, I'm learning for my last exam and used to enjoy a movie at the end of a hard working day...so far...
