1) Only one thread of my i7-2600K seems to be working during rendering. It's PAL video cropped, split several times, etc. and transcoded to DVD HQ. Is one thread enough using PAL? It's fast, but I'd expect more threads being used.
2) PD9 freezes for several seconds when I move timeline pointer too fast. This lag is not so long when I disable Hardware decoding because I use IGP of my CPU (see above) for its Quick Sync feature (it's enabled). Is it caused by low power of graphics needed for decoding? I can use my GTX460 for decoding and switch to IGP for rendering but it's not convenient enough.
