Do the math yourself.

I, for one, am not surprised.

Hi Thomas,

If you meant to reach the bug submitter, you need to use the address:


Yes, I saw my mistake the second I had clicked "send".

Anyway, here's another point: Xv was not supported *at all* on the 6326 with 4.2. Hence, video applications were using another method (probably xshm) by default.

I added Xv support for the 5597/5598/6326/530/620 in September 2002, so it wasn't there before 4.3. (For a detailed changelog, see http://www.winischhofer.net/sis630old.shtml)

Now, with 4.3, applications are using Xv, which takes extra memory for the video frame - which simply isn't available.

Option "NoXvideo" should restore the old behavior.

This is 2004. Video applications not having any fallback algorithm in case of a failure with one of the methods are a shame at least.
