Build 65: TV channel changes have slowed considerably with recent builds. It used to take a couple of seconds, now it's around 5.
When I initiate a channel change, I see the OSD immediately, followed by a lengthy pause... Playback resumes briefly (for about half a second) and THEN the new channel is actually tuned. As I said, the whole thing takes around 5 secs.
I reverted to an older build (49), and performance is considerably better.
Yaobing, let me know if you need a log.
Thanks.
