Hi Yaobing,
FYI - I've been trying to track down some stability issues
and for now I've removed my PCI based DVICO Card and am using a the DVICO NANO USB device (I think I've got a overheating issue in a crampted Dell case but we will see). Anyway, I have noticed the following issues that are common regardless of what device I use. Unfortunaly I've missed the log that had MC being "unresponsive" just after starting a scheduled recording, but I've sent another log file (LOG.ZIP) that may show:
1) Stuttering during CH aquisition: When you select a CH to play, the Video/Sound comes on then freeses for a second, plays for a second, freeses for a second, then plays fine. Repeatable on every CH, every time. On one occasion in the Log (a CH10 Tune) you may see that it just stayed on a freeze (still pic, no sound) - yet MC was responsive and I could "STOP" and restart the CH just fine.
2) Analogue Audio Connection Flashes: I've got my HTPC hooked up to my Yami AV Receiver using S/PDIF. When I enter the "TV" page in Theater View my Yami's PCM light starts flashing very quickly for a second or so (indicating that the source is coming in & out). The same behaviour happens when you STOP a TV Channel that was using PCM. I've not seen this "flashing" behaviour at any other time.
Thanks
Nathan
