We did the test on a 64-bit system, both locally and with X forwarding to a remote machine. It works in both cases. Our TV card is "Avermedia AverTV Super 007" pure analog. Yours is a hybrid analog/ISDB card. Does your card work with videobuf 1? Perhaps you could do such a test: please use code from the commit f73e66a8e91e4ebb "v4l: saa7134: remove radio, vbi, mpeg, input, alsa, tvaudio, saa6752hs support" and see if you TV card works with videobuf (not videobuf2)?
