Hmm, maybe the notification is broken? Or the people reporting the
problem are ignoring these messages?

There is no way 188000 bytes is enough of a buffer for HDTV capture...
We use almost 10 MB for other HDTV capture methods, and the minimum
we allow people to set it to via the UI is almost 5 MB...
