This is my second HD DVD player. When I saw the 8 free hd dvd deal, I decided to get the better version and use the other one for the bedroom. The quality is still as great, if not better for 1080p. The process to firmware upgrade (menu selection and agreement screens) seems to load faster than the HD-A2. Overall, it still promises the great image and sound for HD DVD for a low price!
Note of caution. If you own a 720p/1080i TV, do not bother with the HD-A20 unless you plan to upgrade your TV to 1080p within 1-2 years. Why? Because the HD-A2 does as great a job for a 720p/1080i TV for even lower cost! If you have a 1080p TV that does great interlacing, and you want to go for the low cost alternative, this will do a great job considering the next firmware upgrade will allow 1080p24. But if you still think it's expensive, then go with the HD-A2. Even though it outputs 1080i at most, your 1080p TV should be able to turn the 1080i signal into near 1080p imaging so you cannot really tell the difference between to two. Either way, HD-A2 or HD-A20 is the way to go for low budget, high value, high definition enjoyment!
