I have found that the Medium (Default) setting will not change. You can set it to CBR and 3000 and in the config it says it's changed but it will record using the VBR default settings for Medium. The High and Low setting will record as you set them but the medium does what it wants.
Now i have test and use all thing and diferent setup !
have use a lot moore than 200 hours and the only sensible i can understand
is that the last card you should buy is the 150mce.
i have test it in 3 diferent computors all 3000mz one intel chipset
one via and one nvidia and both with 1 or 2 card setup and in gbpvr
wintv 2000 and my recorded file is always always the same shit that i cant
convert to divx in 2-pass .
but when i plugged in my pvr 350 the recording qality is at least 100%
better or moor maby 200% too.
the chipset the 150mce use is Conexant CX23416 and that is a lowbuget
chip they produse after Conexant CX23415 that pvr250 and pvr350 used
and another thing is that the 150mce isent maked to deliver a mpeg or a
mpg movie file, they use a format they call (DVR-ms) and that is a mirosoft
protected format.
i have sent a question to divx to see if they can analyse a file that i have recorded and see what´s wrong in it.
