beginner needs help...codec problem with bsplayer

[vladgliga]

Well, the quality of the files is ok, I double-checked them on other compuers and also worked on mine just fine before the system crash.

The only programs installed are divx 3.11, ffd show (without changing any options from the default ones), ac3 filters and some nvidia drivers, but i guess does are harmless.

The filters, as in options, are different depending on the files i play.
I mean, some worked and some were upside down before the ffdshow instalation.
For those who worked before (but still low quality)
Default DirectSound device
ffdshow audio decoder
ffdshow mpeg4


as for the video rendering... where am i supposed to operate those changes? sorry agin for being so non-skilled,,,
For those who were upside down
Default direct sound device
ffdshow mpeg4

at options-> filters-> advanced, i see that some drivers that are shaded uin the filter expansion, have a "quartz.dll", size and version specified.
