Hardware Video Capture Test
Using the Hauppauge TV Tuner card we recorded a 20 minute video documentary from a VHS video. We again used Throttle Watch to record the CPU usage under this exercise.
Using the hardware based capture we had no problems with the EPIA EX setup - CPU usage we down to an acceptable level to avoid jumping when encoding, and thanks to a fast SATA HDD there was plenty of speed for the system to dump the recordings straight to the HDD without tying up the system memory too much.
Software Video Capture Test
This time we ran the same VHS video though the USB based TV tuner to see what happens if you went an external TV tuner option or used a PCI based one that has no hardware encode options. Throttle Watch again was used for CPU measurements.
CPU usage went through the roof here.
While the CX700M2 has DivX and MPEG-2 hardware decoding capabilities, it has no encoding abilities and it relies on the CPU to do this fully.
Watching the movie without recording was fine, but when recording, the picture jumped and the audio stuttered, when played back, it was extremely jumpy and audio was well out of sync with what video was recorded. The AMD system also has some jumps but VIA's setup really suffered.
