Hi there,
I am currently investigating ways to reduce the TV channel switch time. I noticed that the TVserver process creates about 100MB of disk activity (mostly read) when I change channels. Then I used ProcessMonitor to find out which files are read and why. Below you see an extract of the log. You see that TVserver does some 2,000,000 byte reads that look strange to me. Is this behavior correct or maybe some dead code?
Regards
Frank
