Can one of the developers please confirm if this issue is known and if they are looking into it? I'm asking because I'm thinking of switching back to "0.2.3.0 RC3" and working through the patches to see where all of this started.
Yes FF/Rewind used to work with preview. I am running just standalone MP and all my videos ad recorded TV do not display preview during FF/Rewind. This problem appears at some point after the release of RC3.
I've just some tests/experiments onmy standalone install . I Found that if you have the EVR set to ENABLED in the "Direct Show Filter Control" section in MP Config then ff/rwd don't work (curtainly not with my ATI card, an X850).
OK, I've solved my problem....so now F-FWD works as it is supposed to....I'm so happy
It was related to my ATI HD 2600 XT drivers, or something that installs with the drivers. I un-installed all the ATI catalyst components, including CCC (Catalyst Control Centre) and the "WDM Drivers". The only thing I left was the actual Graphics-Drivers, and that solved it.
So just to make sure that it wasn't something that got corrupted I re-installed all the ATI components again to see what happens...and as expected F-Fwd stopped working again. Un-installed it again and F-FWD works again.....even with full hardware acceleration enabled..
