[QUOTE="BigBuddha, post: 40109, member: 14670"] [b]Hauppauge 150/500 MCE PQ HUGELY IMPROVED[/b] Hi All, I came across some interesting information from another forum dedicated to Hauppauge cards. Apparently in the most recent drivers available for the 150/500 MCE cards, Hauppauge decided to turn the comb filter off completely. The comb filter is what tries to turn a composite signal into something resembling an S-Video signal. My HD Plasma must have an awesome comb filter in it and this is why the composite signal put into it was so much better than when the same composite signal was put into the Hauppauge. I downloaded some registry tweaks that enable the comb filter and allow you to try some different settings. The result was nothing short of AMAZING. Whilst I would not say that the PQ was perfect, I would at least go as far to say that the improvement was off the scale compared to the PQ I had previously. On the downside, when I got the best PQ after tryng the different registry tweak files, there was a VERY noticable increase in dot crawl. Luckily this was 99.99% limited to the OSD of the STB that I cam capturing the signal from so for me it is not an issue!. Finally, (after finding out all this good info) I found a way to get my Foxtel Cable STB to output a S-Video signal and the PQ is perfect (or at least as good as DVD quality). I still thought it was worth posting the ways to get the best picture when using the composite input. But as everybody has told me, the S-Video input (wich does not make use of the comb filter, because it is not neccessary) is by FAR the best PQ I have seen my PVR 150MCE produce. I will post the links to the topic that I discussed this in as well as some other relevant links about the issue. I will also place a link to the registry tweak files. The first one is the topic that I discussed this whole matter about with another user on the Hauppauge unofficial forum: [url]http://www.shspvr.com/smf/index.php?topic=9618[/url] The second link (in a uk Hauppauge forum) details a discussion about whether the comb filter should be on or off: [url]http://www.hauppauge.co.uk/board/showthread.php?t=6083[/url] This link contains some links to some comb filter tweaks: [url]http://www.shspvr.com/smf/index.php?topic=9170.0[/url] This last link is to an archive I am hosting ( I am hoping that I can get somone else to host it permanantly, it is only 2.14KB in size) and have created that contains all of the registry comb filter tweak files and a description of what each file does: [url]http://www.harmonycentral.com.au/downloads/PVR150Combfix.zip[/url] Lastly, I would like to say a BIG thank you to all of the people who have shared their time and tried to hep me with this problem that I have struggled with for so long. Thanks, BigBuddha [/QUOTE]
