What does your TV have to do with your dvd-writer? I have had a bad Philips dvd-recorder, so I will not likely buy a new dvd recorder of that brand, but I love their dvd-writers and dvd-standalones. My tv is also a Philips and I wish it would die so I can buy a new one, but it simply keeps working year after year for 16 hours a day.
Sorry if you had a bad experience, but you need to be a bit more specific than 'what happened with firmware (nothing)'. Since I bought my 4163b, at least two new firmwares have arrived. And the only bad burns I had, were with bad media.
