[SOLVED] XVID skipping on BS 2.15 and 2.21

[estugarda]

I have a fresh system install (WinXP Pro SP2 32bit with all updates), BS Player 2.15/2.21 PRO, newest XVID codec 1.1.3, and DIVX codec 6.5.1.
When playing XVID movie in BS (DIVX logo appears in the begining) video skips randomly aprox every 30sec-1min. It just goes too fast for a second or two, while sound is OK. What is this?

PS Already tried with other codec versions, and BS versions. Other players work fine I think. Note that this all was working for me on the old system which was completely the same as this new one, except now I have bigger and faster hard drive.
