	I have a shuttle sb61g2 with a Nova-T DVB-T PCI card
	(the one with the grey remote) and an AVerMedia AverTV
	DVB-T USB 2.0 (A800).

	It looks like budget-ci.c module has problems similar
	to the a800 with auto repeat. A colleague of mine made
	some changes to the code to allow better handling
	of the repeats and I've been manually applying his
	changes each time I grab code from CVS.

	I'm no driver coder so I don't fully understand what
	his changes entail or whether they make sense for
	all supported remotes, however it does make my
	grey hauppauge remote work wonderfully well. His
	method of selecting the keycodes was via a simple
	hash define (might be better using a module parameter
	IMHO). Anyway I just thought I'd send you the diffs
	to let you see them. This is for my Hauppauage Nova-T
	DVB-T card.

	As I said, I also have a AVerMedia AverTV DVB-T
	USB 2.0 (A800) so I'm looking forward to any fixes
	for it's remote making their way into CVS. 

	The other thing I've noticed with my a800 is that
	tzap works flawlessly with great quality, but
	when I use it with MythTV 0.18.1 it often fails to
	get FE_LOCK or the picture is very garbled. The
	Nova-T using the same antenna and tzap has no
	problems with either card.

	Is there any reason tzap would work while MythTV
	has issues ? 

	Any thoughts much appreciated.
