Hey,
I use my Hauppauge HVR2200 for analog-TV an DVB-T. Whe I switch from a DVBT-channel to an analog-channel some times crashes Mediaportal with a black screen. I must boot the HTPC. (blank row in TV-log)
When Mediaportal not chrashes, the channel change is very long (10s). Bevor the change comes to the end a short "blub" can I hear. The loudness of an analog channel is lower then a DVBT-channel.
I have changed the HVR2200 driver som times. With all drivers the same result.
