I use tvtime often to watch TV on my monitor, and it works OK, no artifacts and no slowdown (even when I download my email and spamassassin starts to eat CPU cicles like mad).
With my current configuration tvtime at full screen (1024x768) takes about 40% CPU from a AMD XP 1477 MHz (1700 rating). I have just tried launching three copies of "yes" on several aterm's and tvtime still looks as smooth as before, althoug CPU is always at 100%
Please ask for more information should you need it.
