EVR + Analog cable = severe audio lag (1 Viewer)

[andjun]

Encountered what appears to be a bug. If I turn on EVR and tune into one of my analog cable channels, the audio starts to lag and it gets worse the longer you watch the channel. Within 30 seconds, the audio lags with around 4-5 seconds. If I switch to a digital cable channel (ATCS/QAM) the lag disappears and the audio stays in sync.

However, if I switch from EVR to VMR9, I never see any audio lag on analog cable channels.

Any ideas? Thanks in advance for any help.
