Same format(mpeg1) but opened by different decoders

[kimiraikkonen]

My default MPEG1 decoder is quartz.dll (default decoder of Windows). After installing Elecard MPEG-2 Decoder&Streaming Pack 1.0.50824, some of my MPEG1 files is opened by Elecard, some of MPEG1 files are opened by quartz.dll (default Windows's decoder).

Why? How can i choose decoder for every MPEG1 file if there is a difference when opening the same format file???

Additionaly, quartz.dll runs smoother than Elecard when Playing MPEG1 files, also if i select "internal renderer overlay" in BSPLAYER as rendering mode when using Elecard, the video does not play, it gets weird colors and lines like scratched. So i had to change rendering mode to "overlay mixer" valid for only Elecard.

Please post your helps and comments.

I only tested this issue on: Celeron 800, 128 MB SD-RAM, Trident Cyberblade VGA 8MB shared memory.

Best regards.
