Recording

Driver errors might occur when switching between transmitting to
and capturing from the DV device. This problem seems to occur more
frequently with certain DV devices. This problem occurs because the
OHCI driver can intermittently get into a bad mode when the input
and output mode of the driver changes. When you have a device
connected to your system and the video display settings are set to
“send data to the DV device”, and you have real-time effects disabled,
before switching between transmit and capture, first close the Record
Tool window. This will enable the driver to easily switch between
transmit and capture modes. When the driver gets into this bad state,
several things can indicate this:
• The timecode window in the Record tool continually displays
“waiting” and the device no longer accepts device control
commands.
• Playback in the Composer monitor plays for a few seconds,
then hangs, and will typically respond with an ADM overrun
error. Playback from the Composer monitor will do this
consistently.
The Record tool continually responds with “no input signal
present” when in fact, a DV device is connected to the system.
Workaround: Cycle the power on your DV device. If the error persists
after cycling the power on the DV device, reboot your system to force
the TI driver to restart.

Recording across timecode breaks sometimes fails when using a
transcoder.

Video and audio might stutter during pass through recording.

Autosync with Source timecode does not work properly when
recording through a transcoder. The audio and video are out of sync.
