I also own one of those with the non-SHARP / non-LG tuner. I did further digging and found that the chipset used for tuner/demodulation is actually named M88RS2000 (double "8" instead of 8B). I've confirmed that via several google searches as well as looking into my pcb with a magnifier (picture attached). It is manufactured by Montage Tech, with some product info in the links below (nothing too technical, unfortunately): http://www.montage-tech.com/products_DTV.htm http://www.montage-tech.com/Product_RS2000.html I've sent them an email (infosk@xxxxxxxxxxxxxxxx) asking for info that could help us on building a linux driver for their product. Haven't received any reply yet. So it seems such model of the DM04 is a combination LME2510C+M88RS2000. I had mine running under windows for a day or so without failure due to heat. However I could let it run for longer if that would help with troubleshooting the issue you found with your driver. I also offer myself to alpha-test your linux driver in one of my mythtv linux boxes. Just let me know if that could help. Thanks a lot!
