Cannot play IFO, VOB when Microsoft Video Decoder is disabled - Haisook - 05-12-2012 02:55 PM

I am not able to play IFO files when Microsoft Video Decoder is disabled (I disable it to allow subtitles in mp4 and avi). I get an error in WMP that says "Windows Media Player cannot play DVD video,...etc". If I enable the Microsoft Video Decoder, I can open IFO files.

Also VOB files will not play even if I enable the Microsoft Video Decoder.

I want to mention that I set 64bit player as default in the config tab, because when the 32bit player is set, ALL video types do not play at all, and I get "Class not registered" error. Thought this may have something to do with this issue.

Otherwise, I have all video types playing in WMP with subtitles and all.

Any solution?

Thanks.

Do you choose disable UAC? (user account control)

your 32bit issues are very strange.
I never recommend setting the 64bit player as default, ever.

To try to resolve this I'd like you to uninstall my codecs, set UAC to the default position, reboot your computer and re-install the codecs. Run both apps as an admin then test playback (in the 32bit player)

I did that, and files played well, but just when I opened Settings Applications x64, I got a message "Resetting all codecs to installation defaults". After that, I get the same error "Class not registered".

the 64bit app sets LAV for H264 when it does the reset.
set that to Microsoft - does this fix the error?

(btw, I cannot reproduce this error)

No, it doesn't fix it.

The reason I am trying to get 32bit WMP functioning properly is that in 32bit, there are alternatives to the Microsoft decoder for VOB playback. So using 32bit, you can disable the Microsoft decoder and the PDVD12 decoders will handle vob playback.

To check, you havent set the x64 WMP to default again have you?
