Budget mode in this context mean to grab all pids from the transport
stream. Some devices does not support this, particulary usb 1.1 devices
where the bus is not fast enough. I'm confident that the api must
provide support for configuring pid filters otherwise these devices
couldn't be used. Of course it's possible that this is just not
implemented in the BDA module yet, which is okey.

The caching is done after the access module. The module just need to
tell vlc how much to cache. This is quite easy to do.
