Can you please confirm if these are known bugs?

Hi guys, can you please confirm if these are already known bugs  or if there's something wrong with my FSX:

When watching replays the frames seem to "stutter" (even when they are perfectly good at 30+)

And when taxiing in the default 738, the speed indicator shows as zero.

Cheers

my replays stutter a little bit too. not so much from the tower view, but all others.

i recently had a major issue with deleting flights from my logbook. it seems that if i delete anything from it, FSX won't open at all. i had to re-install and get rid of the old logbook files from my documents and settings folder to get it to work again. has that happened to anyone else?

I get that too, however Im not starting out with great frame rates to begain with.
As far as you speed indicator two causes I can think of
A) You are travelling with the wind; so if the wind is blowing 10kts and your going 10kts you show no speed
B) its really cold and you forgot to turn on your pitot tube heater

For smooth replays.. switch to "locked spot" for the exterior view
