There's actually a thread started a couple of days ago regarding that issue here:http://www.avsforum.com/avs-vb/showthread.php?t=1399690
To summarize, the issue of "limited" writes is quite overblown. Even at 50GB writes per day (~6 hours of buffering), a 40GB 34nm SSD will last 10 years (well, taking into account host writes, it might die sooner than that due to controller failure or something). Granted, if you're the type to just turn off the TV while leaving the HTPC on live TV, you could be writing 192GB per day to the SSD just for live buffer. Even at that usage, though, you're still looking at 2 years for a 40GB SSD. Bigger capacity drives would last longer.
With the high $/GB cost, though, I wouldn't really consider using an SSD for DVR use unless it's only for temporary recordings. The way I see it, if you're already adding a mechanical HDD to your build, it's best to move recorder storage and live TV buffer there. If you're pressed for space, though (e.g. uber-tiny Mini-ITX builds), I wouldn't worry about using the SSD as live TV buffer.
